Catalysts, catalyst systems, and processes of the present disclosure can provide polymers having a high comonomer content (e.g., 12 wt % or greater).

(4) For the purposes of the present disclosure, the numbering scheme for the Periodic Table Groups is used as described in Chemical and Engineering News, v. 63(5), pg. 27 (1985). Therefore, a “group 4 metal” is an element from group 4 of the Periodic Table, e.g., Hf, Ti, or Zr.

(5) The specification describes transition metal complexes. The term “complex” is used to describe molecules in which an ancillary ligand is coordinated to a central transition metal atom. The ligand is bulky and stably bonded to the transition metal so as to maintain its influence during use of the catalyst, such as polymerization. The ligand may be coordinated to the transition metal by covalent bond and/or electron donation coordination or intermediate bonds. The transition metal complexes are generally subjected to activation to perform their polymerization or oligomerization function using an activator which, without being bound by theory, is believed to create a cation as a result of the removal of an anionic group, often referred to as a leaving group, from the transition metal.

(6) A metallocene catalyst compound is a transition metal catalyst compound having one, two or three, typically one or two, substituted or unsubstituted cyclopentadienyl ligands bound to the transition metal, typically a metallocene catalyst is an organometallic compound containing at least one π-bound cyclopentadienyl moiety (or substituted cyclopentadienyl moiety).

(7) As used herein, “olefin polymerization catalyst(s)” refers to any catalyst, such as an organometallic complex or compound that is capable of coordination polymerization addition where successive monomers are added in a monomer chain at the organometallic active center.

(8) The terms “substituent,” “radical,” “group,” and “moiety” may be used interchangeably.

(9) As used herein, and unless otherwise specified, the term “Cn” means hydrocarbon(s) having n carbon atom(s) per molecule, wherein n is a positive integer.

(10) As used herein, and unless otherwise specified, the term “hydrocarbon” means a class of compounds containing hydrogen bound to carbon, and encompasses (i) saturated hydrocarbon compounds, (ii) unsaturated hydrocarbon compounds, and (iii) mixtures of hydrocarbon compounds (saturated and/or unsaturated), including mixtures of hydrocarbon compounds having different values of n.

(11) “Catalyst productivity” is a measure of how many grams of polymer (P) are produced using a polymerization catalyst including W g of catalyst (cat), over a period of time of T hours; and may be expressed by the following formula: P/(T×W) and expressed in units of gP/gcat/hr. Conversion is the amount of monomer that is converted to polymer product, and is reported as mol % and is calculated based on the polymer yield and the amount of monomer fed into the reactor. Catalyst activity is a measure of how active the catalyst is and is reported as the mass of product polymer (P) produced per mole of catalyst (cat) used per hour (kgP/molcat/hr).

(12) “BOCD” refers to a Broad Orthogonal Composition Distribution in which the comonomer of a copolymer is incorporated predominantly in the high molecular weight chains or species of a polyolefin polymer or composition. The distribution of the short chain branches can be measured (as an indicator of comonomer content), for example, using Temperature Rising Elution Fractionation (TREF) in connection with a Light Scattering (LS) detector to determine the weight average molecular weight of the molecules eluted from the TREF column at a given temperature. The combination of TREF and LS (TREF-LS) yields information about the breadth of the composition distribution and whether the comonomer content increases, decreases, or is uniform across the chains of different molecular weights of polymer chains. BOCD has been described, for example, in U.S. Pat. No. 8,378,043, Col. 3, line 34, bridging Col. 4, line 19, and U.S. Pat. No. 8,476,392, line 43, bridging Col. 16, line 54.

For purposes of this specification and the claims appended thereto, when a polymer or copolymer is referred to as including an olefin, the olefin present in such polymer or copolymer is the polymerized form of the olefin. For example, when a copolymer is said to have an “ethylene” content of 35 weight % (wt %) to 55 wt %, it is understood that the mer unit in the copolymer is derived from ethylene in the polymerization reaction and said derived units are present at 35 wt % to 55 wt %, based upon the weight of the copolymer. A “polymer” has two or more of the same or different mer units. A “homopolymer” is a polymer having mer units that are the same. A “copolymer” is a polymer having two or more mer units that are different from each other. A “terpolymer” is a polymer having three mer units that are different from each other. Accordingly, the definition of copolymer, as used herein, includes terpolymers and the like. “Different” is used to refer to mer units indicates that the mer units differ from each other by at least one atom or are different isomerically. An “ethylene polymer” or “ethylene copolymer” is a polymer or copolymer including at least 50 mol % ethylene derived units, a “propylene polymer” or “propylene copolymer” is a polymer or copolymer including at least 50 mol % propylene derived units, and so on.

When “catalyst system” is used to describe such the catalyst compound/activator combination before activation, it means the unactivated catalyst complex (precatalyst) together with an activator and, optionally, a co-activator. When it is used to describe the combination after activation, it means the activated complex and the activator or other charge-balancing moiety. The transition metal compound may be neutral as in a precatalyst, or a charged species with a counter ion as in an activated catalyst system. For the purposes of the present disclosure, when catalyst systems are described as including neutral stable forms of the components, it is well understood by one of ordinary skill in the art, that the ionic form of the component is the form that reacts with the monomers to produce polymers. Furthermore, catalyst compounds represented by formulae herein embrace both neutral and ionic forms of the catalyst compounds.

(21) In the description herein, the catalyst may be described as a catalyst precursor, a pre-catalyst compound, catalyst compound or a transition metal compound, and these terms are used interchangeably. A polymerization catalyst system is a catalyst system that can polymerize monomers to polymer. An “anionic ligand” is a negatively charged ligand which donates one or more pairs of electrons to a metal ion. A “neutral donor ligand” is a neutrally charged ligand which donates one or more pairs of electrons to a metal ion. Activator and cocatalyst are also used interchangeably.

(22) A scavenger is a compound that may be added to facilitate polymerization by scavenging impurities. Some scavengers may also act as activators and may be referred to as co-activators.

The term NCA is also defined to include neutral Lewis acids, such as tris(pentafluorophenyl)boron, that can react with a catalyst to form an activated species by abstraction of an anionic group. An NCA coordinates weakly enough that a neutral Lewis base, such as an olefinically or acetylenically unsaturated monomer can displace it from the catalyst center. Any metal or metalloid that can form a compatible, weakly coordinating complex may be used or contained in the non-coordinating anion. Suitable metals include, but are not limited to, aluminum, gold, and platinum. Suitable metalloids include, but are not limited to, boron, aluminum, phosphorus, and silicon.

(37) Where isomers of a named alkyl, alkenyl, alkoxide, or aryl group exist (e.g., n-butyl, iso-butyl, sec-butyl, and tert-butyl) reference to one member of the group (e.g., n-butyl) shall expressly disclose the remaining isomers (e.g., iso-butyl, sec-butyl, and tert-butyl) in the family. Likewise, reference to an alkyl, alkenyl, alkoxide, or aryl group without specifying a particular isomer (e.g., butyl) expressly discloses all isomers (e.g., n-butyl, iso-butyl, sec-butyl, and tert-butyl).

(38) The term “ring atom” means an atom that is part of a cyclic ring structure. By this definition, a benzyl group has six ring atoms and tetrahydrofuran has 5 ring atoms.

(39) A heterocyclic ring is a ring having a heteroatom in the ring structure as opposed to a heteroatom substituted ring where a hydrogen on a ring atom is replaced with a heteroatom. For example, tetrahydrofuran is a heterocyclic ring and 4-N,N-dimethylamino-phenyl is a heteroatom-substituted ring.

(40) The term “continuous” means a system that operates without interruption or cessation. For example, a continuous process to produce a polymer would be one where the reactants are continually introduced into one or more reactors and polymer product is continually withdrawn until the polymerization is stopped, e.g. at 300 minutes.

(41) A solution polymerization means a polymerization process in which the polymer is dissolved in a liquid polymerization medium, such as an inert solvent or monomer(s) or their blends. A solution polymerization is homogeneous. A homogeneous polymerization is one where the polymer product is dissolved in the polymerization medium. Suitable systems may not turbid as described in Oliveira, J. V. et al. (2000) Ind. Eng. Chem. Res., v. 39(12), pp. 4627-4633.

(42) A bulk polymerization means a polymerization process in which the monomers and/or comonomers being polymerized are used as a solvent or diluent using little or no inert solvent as a solvent or diluent. A small fraction of inert solvent might be used as a carrier for catalyst and scavenger. A bulk polymerization system contains less than 25 wt % of inert solvent or diluent, such as less than 10 wt %, such as less than 1 wt %, such as 0 wt %.

(43) U.S. Pat. No. 9,290,593 ('593 patent) describes BOCD Index. The BOCD Index may be described by the following equation:
BOCD Index=(Content of SCB at the high molecular weight side−Content of SCB at the low molecular weight side)/(Content of SCB at the low molecular weight side),
where the “Content of SCB at the high molecular weight side” means the content of the SCB (the number of branches/1,000 carbon atoms) included in a polymer chain having a molecular weight of Mw of the polyolefin or more and 1.3×Mw or less, and the “Content of SCB at the low molecular weight side” means the content of the SCB (the number of branches/1,000 carbon atoms) included in a polymer chain having a molecular weight of 0.7×Mw of the polyolefin or more and less than Mw. The BOCD Index defined by the equation above may be in the range of 1 to 5, such as 2 to 4, such as 2 to 3.5. See, also, FIG. 1 and FIG. 2 of the '593 patent (characterizing BOCD polymer structures using GPC-FTIR data).

(44) The breadth of the composition distribution can be characterized by the T.sub.75-T.sub.25 value, where T.sub.25 is the temperature at which 25% of the eluted polymer is obtained and T.sub.75 is the temperature at which 75% of the eluted polymer is obtained in a TREF experiment. The composition distribution is further characterized by the F.sub.80 value, which is the fraction of polymer that elutes below 80° C. in a TREF-LS experiment. A higher F.sub.80 value indicates a higher fraction of comonomer in the polymer molecule. An orthogonal composition distribution is defined by a M.sub.60/M.sub.90 value that is greater than 1, where M.sub.60 is the molecular weight of the polymer fraction that elutes at 60° C. in a TREF-LS experiment and M.sub.90 is the molecular weight of the polymer fraction that elutes at 90° C. in a TREF-LS experiment.

(45) In at least one embodiment, a polymer has a BOCD characterized in that the T.sub.75-T.sub.25 value is 1 or greater, 2 or greater, 2.5 or greater, 4 or greater, 5 or greater, 7 or greater, 10 or greater, 11.5 or greater, 15 or greater, 17.5 or greater, 20 or greater, 25 or greater, 30 or greater, 35 or greater, 40 or greater, or 45 or greater, where T.sub.25 is the temperature at which 25% of the eluted polymer is obtained and T.sub.75 is the temperature at which 75% of the eluted polymer is obtained in a TREF experiment.

(46) The polymers as described herein may further have a BOCD characterized in that M.sub.60/M.sub.90 value is 1.5 or greater, 2 or greater, 2.25 or greater, 2.5 or greater, 3 or greater, 3.5 or greater, 4 or greater, 4.5 or greater, or 5 or greater, where M.sub.60 is the molecular weight of the polymer fraction that elutes at 60° C. in a TREF-LS experiment and M.sub.90 is the molecular weight of the polymer fraction that elutes at 90° C. in a TREF-LS experiment as described herein.

(47) Additionally, the polymers as described herein may further have a BOCD characterized in that F.sub.80 value is 1% or greater, 2% or greater, 3% or greater, 4% or greater, 5% or greater, 6% or greater, 7% or greater, 10% or greater, 11% or greater, 12% or greater, or 15% or greater, where F.sub.80 is the fraction of polymer that elutes below 80° C.

Activators

(126) The terms “cocatalyst” and “activator” are used herein interchangeably and are defined to be any compound which can activate any one of the catalyst compounds described above by converting the neutral catalyst compound to a catalytically active catalyst compound cation.

(127) After the catalysts have been synthesized, catalyst systems may be formed by combining the catalysts with activators in any suitable manner, including by supporting them for use in slurry or gas phase polymerization. The catalyst systems may also be added to or generated in solution polymerization or bulk polymerization (in the monomer, such as, without solvent). Suitable catalyst system may contain a transition metal complex as described above and an activator such as alumoxane or a non-coordinating anion activator. Activation may be performed using alumoxane solution including an alkyl alumoxane such as methyl alumoxane, referred to as MAO, as well as modified MAO, referred to herein as MMAO, which contains some higher alkyl groups to improve the solubility. MAO can be purchased from Albemarle Corporation, Baton Rouge, La., such as in a 10 wt % solution in toluene. In at least one embodiment, activators that is used in the catalyst system is or includes one or more alumoxanes, one or more aluminum alkyls, and other aluminum compounds. Suitable activators that can be used in the catalyst system can be or include, but are not limited to, methyl alumoxane, ethyl alumoxane, isobutyl alumoxane, isobutyl alumoxane, trimethyl aluminum, triethyl aluminum, tripropyl aluminum, tributyl aluminum, N,N-dimethylanilinium tetra(perfluorophenyl)borate, N,N-dimethylanilinium tetrakis(perfluoronaphthyl)borate, N,N-dimethylanilinium tetrakis(perfluorobiphenyl)borate, N,N-dimethylanilinium tetrakis(3,5-bis(trifluoromethyl)phenyl)borate, triphenylcarbenium tetrakis(perfluoronaphthyl)borate, triphenylcarbenium tetrakis(perfluorobiphenyl)borate, triphenylcarbenium tetrakis(3,5-bis(trifluoromethyl)phenyl)b orate, triphenylcarbenium tetra(perfluorophenyl)borate, triphenylcarbenium tetrakis(perfluorophenyl)borate, 1-(4-(tris(pentafluorophenyl)borate)-2,3,5,6-tetrafluorophenyl)pyrrolidinium, tetrakis(pentafluorophenyl)borate, 4-(tris(pentafluorophenyl)borate)-2,3,5,6-tetrafluoropyridine, isomers thereof, substitutes thereof, or any combination thereof.

(128) When an alumoxane or modified alumoxane is used, the catalyst-to-activator molar ratio is from about 1:3,000 to about 10:1; such as about 1:2,000 to about 10:1; such as about 1:1,000 to about 10:1; such as about 1:500 to about 1:1; such as about 1:300 to about 1:1; such as about 1:200 to about 1:1; such as about 1:100 to about 1:1; such as about 1:50 to about 1:1; such as about 1:10 to about 1:1. When the activator is an alumoxane (modified or unmodified), some embodiments select the maximum amount of activator at a 5,000-fold molar excess over the catalyst (per metal catalytic site). The minimum activator-to-catalyst ratio can be 1:1 molar ratio.

(129) Activation may also be performed using non-coordinating anions, referred to as NCA's, of the type, such as described in EP0277003A1 and EP0277004A1. NCA may be added in the form of an ion pair using, such as [DMAH]+ [NCA]− in which the N,N-dimethylanilinium (DMAH) cation reacts with a basic leaving group on the transition metal complex to form a transition metal complex cation and [NCA]−.

For purposes of the claims to this invention the following DSC procedure shall be used:

(201) Differential Scanning calorimetry. Melting Temperature, Tm, is measured by differential scanning calorimetry (“DSC”) using a DSCQ200 unit. The sample is first equilibrated at 25° C. and subsequently heated to 220° C. using a heating rate of 10° C./min (first heat). The sample is held at 220° C. for 3 minutes. The sample is subsequently cooled down to −100° C. with a constant cooling rate of 10° C./min (first cool). The sample is equilibrated at −100° C. before being heated to 220° C. at a constant heating rate of 10° C./min (second heat). The exothermic peak of crystallization (first cool) is analyzed using the TA Universal Analysis software and the corresponding to 10° C./min cooling rate is determined. The endothermic peak of melting (second heat) is also analyzed using the TA Universal Analysis software and the peak melting temperature (Tm) corresponding to 10° C./min heating rate is determined.

(203) Molecular Weight, Comonomer Composition and Long Chain Branching Determination by Polymer Char GPC-IR Hyphenated with Multiple Detectors

(204) For purposes of the claims, and unless otherwise indicated, the distribution and the moments of molecular weight (Mw, Mn, Mz, Mw/Mn, etc.), the comonomer content (C.sub.2, C.sub.3, C.sub.6, etc.) are determined by using a high temperature Gel Permeation Chromatography (Polymer Char GPC-IR) equipped with a multiple-channel band-filter based Infrared detector IR5, an 18-angle light scattering detector and a viscometer. Three Agilent PLgel 10-μm Mixed-B LS columns are used to provide polymer separation. Aldrich reagent grade 1,2,4-trichlorobenzene (TCB) with 300 ppm antioxidant butylated hydroxytoluene (BHT) is used as the mobile phase. The TCB mixture is filtered through a 0.1-μm Teflon filter and degassed with an online degasser before entering the GPC instrument. The nominal flow rate is 1.0 ml/min and the nominal injection volume is 200 μL. The whole system including transfer lines, columns, and detectors are contained in an oven maintained at 145° C. Given amount of polymer sample is weighed and sealed in a standard vial with 80-4 flow marker (Heptane) added to it. After loading the vial in the autosampler, polymer is automatically dissolved in the instrument with 8 ml added TCB solvent. The polymer is dissolved at 160° C. with continuous shaking for about 1 hour for most polyethylene samples or 2 hours for polypropylene samples. The TCB densities used in concentration calculation are 1.463 g/ml at room temperature and 1.284 g/ml at 145° C. The sample solution concentration is from 0.2 to 2.0 mg/ml, with lower concentrations being used for higher molecular weight samples. The concentration (c), at each point in the chromatogram is calculated from the baseline-subtracted IR5 broadband signal intensity (I), using the following equation: c=βI, where β is the mass constant. The mass recovery is calculated from the ratio of the integrated area of the concentration chromatography over elution volume and the injection mass which is equal to the pre-determined concentration multiplied by injection loop volume. The conventional molecular weight (IR MW) is determined by combining universal calibration relationship with the column calibration which is performed with a series of monodispersed polystyrene (PS) standards ranging from 700 to 10M gm/mole. The MW at each elution volume is calculated with following equation:

(205) $\log M=\frac{\log \left(K_{\mathrm{PS}}/K\right)}{\alpha +1}+\frac{{\alpha }_{\mathrm{PS}}+1}{\alpha +1}\log M_{\mathrm{PS}}$
where the variables with subscript “PS” stand for polystyrene while those without a subscript are for the test samples. In this method, α.sub.PS=0.67 and K.sub.PS=0.000175, while a and K for other materials are as calculated and published in literature (Sun, T. et al. (2001) Macromolecules, v. 34(19), pp. 6812-6820), except that for purposes of this invention and claims thereto, α=0.695+(0.01*(wt. fraction propylene)) and K=0.000579-(0.0003502*(wt. fraction propylene)) for ethylene-propylene copolymers and ethylene-propylene-diene terpolymers, α=0.695 and K=0.000579 for linear ethylene polymers, α=0.705 and K=0.0002288 for linear propylene polymers, α=0.695 and K=0.000181 for linear butene polymers, α is 0.695 and K is 0.000579*(1-0.0087*w2b+0.000018*(w2b)−2) for ethylene-butene copolymer where w2b is a bulk weight percent of butene comonomer, a is 0.695 and K is 0.000579*(1-0.0075*w2b) for ethylene-hexene copolymer where w2b is a bulk weight percent of hexene comonomer, and α is 0.695 and K is 0.000579*(1-0.0077*w2b) for ethylene-octene copolymer where w2b is a bulk weight percent of octene comonomer. Concentrations are expressed in g/cm.sup.3, molecular weight is expressed in g/mole, and intrinsic viscosity (hence K in the Mark-Houwink equation) is expressed in dL/g unless otherwise noted.

(206) The comonomer composition is determined by the ratio of the IR5 detector intensity corresponding to CH.sub.2 and CH.sub.3 channel calibrated with a series of PE and PP homo/copolymer standards whose nominal value are predetermined by NMR or FTIR. In particular, this provides the methyls per 1,000 total carbons (CH.sub.3/1000TC) as a function of molecular weight. The short-chain branch (SCB) content per 1000TC (SCB/1000TC) is then computed as a function of molecular weight by applying a chain-end correction to the CH.sub.3/1000TC function, assuming each chain to be linear and terminated by a methyl group at each end. The weight % comonomer is then obtained from the following expression in which f is 0.3, 0.4, 0.6, 0.8, and so on for C.sub.3, C.sub.4, C.sub.6, C.sub.8, and so on co-monomers, respectively:
w2=f*SCB/1000TC.

(207) The bulk composition of the polymer from the GPC-IR and GPC-4D analyses is obtained by considering the entire signals of the CH.sub.3 and CH.sub.2 channels between the integration limits of the concentration chromatogram. First, the following ratio is obtained

(208) $\mathrm{Bulk}\mathrm{IR}\mathrm{ratio}=\frac{\mathrm{Area}\mathrm{of}{\mathrm{CH}}_3\mathrm{signal}\mathrm{within}\mathrm{integration}\mathrm{limits}}{\mathrm{Area}\mathrm{of}{\mathrm{CH}}_2\mathrm{signal}\mathrm{within}\mathrm{integration}\mathrm{limits}}.$

(209) Then the same calibration of the CH.sub.3 and CH.sub.2 signal ratio, as mentioned previously in obtaining the CH3/1000TC as a function of molecular weight, is applied to obtain the bulk CH3/1000TC. A bulk methyl chain ends per 1000TC (bulk CH3end/1000TC) is obtained by weight-averaging the chain-end correction over the molecular-weight range. Then
w2b=f*bulk CH3/1000TC
bulk SCB/1000TC=bulk CH3/1000TC−bulk CH3end/1000TC
and bulk SCB/1000TC is converted to bulk w2 in the same manner as described above.

(210) The LS detector is the 18-angle Wyatt Technology High Temperature DAWN HELEOSII. The LS molecular weight (M) at each point in the chromatogram is determined by analyzing the LS output using the Zimm model for static light scattering (Light Scattering from Polymer Solutions; Huglin, M. B., Ed.; Academic Press, 1972.):

(211) $\frac{K_{o}c}{\Delta R\left(\theta \right)}=\frac{1}{\mathrm{MP}\left(\theta \right)}+2A_{2}c.$
Here, ΔR(θ) is the measured excess Rayleigh scattering intensity at scattering angle θ, c is the polymer concentration determined from the IR5 analysis, A2 is the second virial coefficient, P(θ) is the form factor for a monodisperse random coil, and K.sub.O is the optical constant for the system:

(212) $K_o=\frac{4{\pi }^2{n^2\left(\mathrm{dn}/dc\right)}^2}{{\lambda }^4{N}_A}$
where N.sub.A is Avogadro's number, and (dn/dc) is the refractive index increment for the system. The refractive index, n=1.500 for TCB at 145° C. and λ=665 nm. For analyzing ethylene homopolymers, ethylene-hexene copolymers, and ethylene-octene copolymers, dn/dc=0.1048 ml/mg and A.sub.2=0.0015; for analyzing ethylene-butene copolymers, dn/dc=0.1048*(1−0.00126*w2) ml/mg and A.sub.2=0.0015 where w2 is weight percent butene comonomer.

(213) In at least one embodiment, the polymer produced herein has a unimodal or multimodal molecular weight distribution as determined by Gel Permeation Chromatography (GPC). By “unimodal” is meant that the GPC trace has one peak or inflection point. By “multimodal” is meant that the GPC trace has at least two peaks or inflection points. An inflection point is that point where the second derivative of the curve changes in sign (e.g., from negative to positive or vice versus).

(214) In at least one embodiment, a bimodal polymer, such as a bimodal polyethylene (e.g., formed by a catalyst system having a catalyst represented by Formulas (II), (V), (VI) and (VII) and another type of catalyst, such as, for example, a metallocene catalyst) has an Mw/Mn value from about 1 to about 10, such as from about 1.5 to about 8, such as from about 2 to about 4, such as from about 2 to about 3.

(215) In at least one embodiment, the polymer produced herein has a composition distribution breadth index (CDBI) of 50% or more, such as 60% or more, such as 70% or more. CDBI is a measure of the composition distribution of monomer within the polymer chains and is measured by the procedure described in PCT publication WO 1993/003093, published Feb. 18, 1993, specifically columns 7 and 8 as well as in Wild, L. et al. (1982) J. Poly. Sci., Poly. Phys. Ed., v 20, pp. 441-455 and U.S. Pat. No. 5,008,204, including that fractions having a weight average molecular weight (Mw) below 15,000 are ignored when determining CDBI.

(216) Blends

(217) In at least one embodiment, the polymer (such as polyethylene or polypropylene) produced herein is combined with one or more additional polymers prior to being formed into a film, molded part or other article. Other useful polymers include polyethylene, isotactic polypropylene, highly isotactic polypropylene, syndiotactic polypropylene, LDPE, LLDPE, HDPE, random copolymer of ethylene and propylene, and/or butene, hexene, polybutene, ethylene vinyl acetate, ethylene vinyl acetate, ethylene methyl acrylate, copolymers of acrylic acid, polymethylmethacrylate or any other polymers polymerizable by a high-pressure free radical process, polyvinylchloride, polybutene-1, isotactic polybutene, ABS resins, ethylene-propylene rubber (EPR), vulcanized EPR, EPDM, block copolymer, styrenic block copolymers, polyamides, polycarbonates, PET resins, cross linked polyethylene, copolymers of ethylene and vinyl alcohol (EVOH), polymers of aromatic monomers such as polystyrene, poly-1 esters, polyacetal, polyvinylidine fluoride, polyethylene glycols, and/or polyisobutylene.

(218) In at least one embodiment, the polymer (such as polyethylene or polypropylene) is present in the above blends, at from 10 to 99 wt %, based upon the weight of the polymers in the blend, such as 20 to 95 wt %, such as at least 30 to 90 wt %, such as at least 40 to 90 wt %, such as at least 50 to 90 wt %, such as at least 60 to 90 wt %, such as at least 70 to 90 wt %.

(219) The blends described above may be produced by mixing the polymers of the present disclosure with one or more polymers (as described above), by connecting reactors together in series to make reactor blends or by using more than one catalyst in the same reactor to produce multiple species of polymer. The polymers can be mixed together prior to being put into the extruder or may be mixed in an extruder.

(220) The blends may be formed using conventional equipment and methods, such as by dry blending the individual components and subsequently melt mixing in a mixer, or by mixing the components together directly in a mixer, such as, for example, a Banbury mixer, a Haake mixer, a Brabender internal mixer, or a single or twin-screw extruder, which may include a compounding extruder and a side-arm extruder used directly downstream of a polymerization process, which may include blending powders or pellets of the resins at the hopper of the film extruder. Additionally, additives may be included in the blend, in one or more components of the blend, and/or in a product formed from the blend, such as a film, as desired. Such additives are well known in the art, and can include, for example: fillers; antioxidants (e.g., hindered phenolics such as IRGANOX™ 1010 or IRGANOX™ 1076 available from Ciba-Geigy); phosphites (e.g., IRGAFOS™ 168 available from Ciba-Geigy); anti-cling additives; tackifiers, such as polybutenes, terpene resins, aliphatic and aromatic hydrocarbon resins, alkali metal and glycerol stearates, and hydrogenated rosins; UV stabilizers; heat stabilizers; anti-blocking agents; release agents; anti-static agents; pigments; colorants; dyes; waxes; silica; fillers; talc; and the like.

(221) Films

(222) Specifically, any of the foregoing polymers, such as the foregoing polyethylenes or blends thereof, may be used in a variety of end-use applications. Such applications include, for example, mono- or multi-layer blown, extruded, and/or shrink films. These films may be formed by any number of extrusion or coextrusion techniques, such as a blown bubble film processing technique, wherein the composition can be extruded in a molten state through an annular die and then expanded to form a uni-axial or biaxial orientation melt prior to being cooled to form a tubular, blown film, which can then be axially slit and unfolded to form a flat film. Films may be subsequently unoriented, uniaxially oriented, or biaxially oriented to the same or different extents. One or more of the layers of the film may be oriented in the transverse and/or longitudinal directions to the same or different extents. The uniaxial orientation can be accomplished using cold drawing or hot drawing methods. Biaxial orientation can be accomplished using tenter frame equipment or a double bubble processes and may occur before or after the individual layers are brought together. For example, a polyethylene layer can be extrusion coated or laminated onto an oriented polypropylene layer or the polyethylene and polypropylene can be coextruded together into a film then oriented. Likewise, oriented polypropylene could be laminated to oriented polyethylene or oriented polyethylene could be coated onto polypropylene then optionally the combination could be oriented even further. For example, the films are oriented in the Machine Direction (MD) at a ratio of up to 15, such as between 5 and 7, and in the Transverse Direction (TD) at a ratio of up to 15, such as 7 to 9. However, in at least one embodiment the film is oriented to the same extent in both the MD and TD directions.

(223) The films may vary in thickness depending on the intended application; however, films of a thickness from 1 to 50 μm are usually suitable. Films intended for packaging are usually from 10 to 50 μm thick. Suitable thickness of the sealing layer can be 0.2 μm to 50 μm. There may be a sealing layer on both the inner and outer surfaces of the film or the sealing layer may be present on only the inner or the outer surface.

(224) In at least one embodiment, one or more layers is modified by corona treatment, electron beam irradiation, gamma irradiation, flame treatment, or microwave. In at least one embodiment, one or both of the surface layers is modified by corona treatment.

Polymerization Examples

(296) General polymerization procedures for parallel pressure reactor. Solvents, polymerization-grade toluene, and isohexane were supplied by ExxonMobil Chemical Company and purified by passing through a series of columns: two 500 cc Oxyclear cylinders in series from Labclear (Oakland, Calif.), followed by two 500 cc columns in series packed with dried 3 Å mole sieves (8-12 mesh; Aldrich Chemical Company), and two 500 cc columns in series packed with dried 5 Å mole sieves (8-12 mesh; Aldrich Chemical Company).

(297) 1-octene (C.sub.8) (98%, Aldrich Chemical Company) was dried by stirring over NaK overnight followed by filtration through basic alumina (Aldrich Chemical Company, Brockman Basic 1).

(298) Polymerization-grade ethylene (C.sub.2) was used and further purified by passing the gas through a series of columns: 500 cm.sup.3 Oxyclear cylinder from Labclear (Oakland, Calif.) followed by a 500 cm.sup.3 column packed with dried 3 Å mole sieves (8-12 mesh; Aldrich Chemical Company) and a 500 cm.sup.3 column packed with dried 5 Å mole sieves (8-12 mesh; Aldrich Chemical Company).

(299) Solutions of the metal complexes and activators were prepared in a drybox using toluene (ExxonMobil Chemical Company; anhydrous, stored under nitrogen; 98%). Concentrations were 0.2 mmol/L for the metal complexes and N,N-dimethyl anilinium tetrakis-pentafluorophenyl borate (DMAH-PFPB) and 0.5% w/w for methyl alumoxane (MAO).

(300) Slurries of supported catalysts in toluene were prepared in the drybox using 45 mg of the supported catalyst and 15 mL of toluene. The resulting mixture was vortexed for uniform distribution of particles prior to injection.

(301) For polymerization experiments with supported catalysts or DMAH-PFPB as activator, tri-n-octylaluminum (TNOAL, neat, AkzoNobel) was used as a scavenger. Concentration of the TNOAL solution in toluene ranged from 0.5 to 2 mmol/L.

(302) Polymerizations were carried out in a parallel, pressure reactor, as generally described in U.S. Pat. Nos. 6,306,658; 6,455,316; 6,489,168; WO 2000/009255; and Murphy et al. (2003) J. Am. Chem. Soc., v. 125, pp. 4306-4317, each of which is fully incorporated herein by reference. The experiments were conducted in an inert atmosphere (N2) drybox using autoclaves equipped with an external heater for temperature control, glass inserts (internal volume of reactor=23.5 mL for C2 and C2/C8; 22.5 mL for C.sub.3 runs), septum inlets, regulated supply of nitrogen, ethylene and propylene, and equipped with disposable PEEK mechanical stirrers (800 RPM). The autoclaves were prepared by purging with dry nitrogen at 110° C. or 115° C. for 5 hours and then at 25° C. for 5 hours.

(303) Catalyst systems dissolved in solution were used in the polymerization examples below, unless specified otherwise.

(304) Ethylene-Octene Copolymerization (EO)(see Tables 1 and 2).

(305) A pre-weighed glass vial insert and disposable stirring paddle were fitted to each reaction vessel of the reactor, which contains 48 individual reaction vessels. The reactor was then closed and purged with ethylene. Each vessel was charged with enough solvent (such as isohexane) to bring the total reaction volume, including the subsequent additions, to the desired volume, such as 5 mL. 1-octene, if required, was injected into the reaction vessel and the reactor was heated to the set temperature and pressurized to the predetermined pressure of ethylene, while stirring at 800 rpm. The aluminum and/or zinc compound in toluene was then injected as scavenger and/or chain transfer agent followed by addition of the activator solution (such as 1-1.2 molar equivalents of N,N-dimethyl anilinium tetrakis-pentafluorophenyl borate-DMAH-PFPB).

(306) The catalyst solution (such as 0.020-0.080 μmol of metal complex) was injected into the reaction vessel and the polymerization was allowed to proceed until a pre-determined amount of ethylene (quench value 20 psi) had been used up by the reaction. Alternatively, the reaction may be allowed to proceed for a set amount of time (for example, maximum reaction time 30 minutes). Ethylene was added continuously (through the use of computer controlled solenoid valves) to the autoclaves during polymerization to maintain reactor gauge pressure (+/−2 psig) and the reactor temperature was monitored and maintained within +/−1° C. The reaction was quenched by pressurizing the vessel with compressed air. After the reactor was vented and cooled, the glass vial insert containing the 30 polymer product and solvent was removed from the pressure cell and the inert atmosphere glove box, and the volatile components were removed using a Genevac HT-12 centrifuge and Genevac VC3000D vacuum evaporator operating at elevated temperature and reduced pressure. The vial was then weighed to determine the yield of the polymer product. The resultant polymer was analyzed by Rapid GPC (see below) to determine the molecular weight, by FT-IR (see below) to determine percent octene incorporation, and by DSC (see below) to determine melting point (Tm).

(307) For polymerizations using MAO as activator (such as 100 to 1,000 molar equivalents), the MAO solution was injected into the reaction vessel after the addition of 1-octene and prior to heating the vessel to the set temperature and pressurizing with ethylene. No additional aluminum reagent was used as scavenger during these runs.

(308) Equivalence is determined based on the mole equivalents relative to the moles of the transition metal in the catalyst complex.

(309) For polymerizations using MAO as activator, the MAO solution was injected into the vessel after the addition of isohexane. No additional aluminum reagent was used as scavenger during these runs.

(310) Polymerizations using Catalysts (Tables 1 and 2). For ethylene-octene copolymerization (EO), the reactor was prepared as described above and purged with ethylene. Isohexane, 1-octene (100 μL), and the scavenger solution were added sequentially to the reaction vessel via syringe at room temperature and atmospheric pressure. If the reactor was heated to the process temperature of 80° C., it was then charged with ethylene to the pressure setpoint of 95 psig (95 psig=655 kPa) while stirring at 800 rpm. If the reactor was then heated to the process temperature of 100° C., it was then charged with ethylene to the pressure setpoint of 135 psig (135 psig=931 kPa) while stirring at 800 rpm. The supported catalyst slurry was injected into the vessel and the polymerization was allowed to proceed as described in the previous section. To test for catalyst response to hydrogen, the EO experiments were also carried out using 300 ppm H.sub.2/5 ethylene mixed gas.

(311) Polymer Characterization. Polymer sample solutions were prepared by dissolving polymer in 1,2,4-trichlorobenzene (TCB, 99+% purity from Sigma-Aldrich) containing 2,6-di-tertbutyl-4-methylphenol (BHT, 99% from Aldrich) at 165° C. in a shaker oven for approximately 3 hours. The concentration of polymer in solution was between 0.1 mg/mL to 0.9 mg/mL with a BHT concentration of 1.25 mg BHT/mL of TCB.

(312) Gel Permeation Chromatography-Tosoh EcoSEC High Temperature GPC System (GPC-Tosoh EcoSEC)—

(313) Mw, Mn and Mw/Mn were determined by using a High Temperature Gel Permeation Chromatography (Tosoh Bioscience, LLC), equipped with a differential refractive index detector (DRI). Three high temperature TSK gel column (Tosoh GMHHR-H(30)HT2) were used. The nominal flow rate was 1 mL/min, and the nominal injection volume was 300 μL. The various transfer lines, columns, and dual flow differential refractometer (the DRI detector) were contained in an oven maintained at 160° C. Solvent for the experiment was prepared by dissolving 1.2 grams of butylated hydroxytoluene as an antioxidant in 4 liters of Aldrich reagent grade 1, 2, 4 trichlorobenzene (TCB). The TCB mixture was then filtered through a 0.1 μm Teflon filter. The TCB was then degassed with an online degasser before entering the GPC instrument. Polymer solutions were prepared by placing dry polymer in glass vials, adding the desired amount of TCB, then heating the mixture at 160° C. with continuous shaking for about 2 hours. All quantities were measured gravimetrically. The injection concentration was from 0.5 to 2 mg/mL, with lower concentrations being used for higher molecular weight samples. Flow rate in the apparatus was then increased to 1 mL/minute, and the DRI was allowed to stabilize for 2 hours before injecting the first sample. The molecular weight was determined by combining universal calibration relationship with the column calibration which was performed with a series of monodispersed polystyrene (PS) standards. The MW was calculated at each elution volume with the following equation:

(314) $\log M_X=\frac{\log \left(K_X/K_{\mathrm{PS}}\right)}{a_x+1}+\frac{a_{\mathrm{PS}}+1}{a_X+1}\log M_{\mathrm{PS}}$
where the variables with subscript “X” stand for the test sample while those with subscript “PS” stand for PS. In this method, a.sub.PS=0.67 and K.sub.PS=0.000175 while a.sub.X and K.sub.X are obtained from published literature. Specifically, a/K=0.695/0.000579 for polyethylene and 0.705/0.0002288 for polypropylene.

(315) The concentration, c, at each point in the chromatogram was calculated from the baseline-subtracted DRI signal, I.sub.DRI, using the following equation:
c=K.sub.DRII.sub.DRI/(dn/dc)
where K.sub.DRI is a constant determined by calibrating the DRI, and (dn/dc) is the refractive index increment for the system. Specifically, dn/dc=0.109 for both polyethylene and polypropylene.

(316) The mass recovery was calculated from the ratio of the integrated area of the concentration chromatography over elution volume and the injection mass which was equal to the pre-determined concentration multiplied by injection loop volume.

(317) All molecular weights are reported in g/mol unless otherwise noted.

(318) Differential Scanning calorimetry (DSC) measurements were performed on a TAQ100 instrument to determine the melting point (Tm) of the polymers. Samples were preannealed at 220° C. for 15 minutes and then allowed to cool to room temperature overnight. The samples were then heated to 220° C. at a rate of 100° C./min and then cooled at a rate of 50° C./min. Melting points were collected during the heating period.

(319) The weight percent of ethylene incorporated in polymers was determined by rapid FTIR spectroscopy on a Bruker Equinox 55+IR in reflection mode. Samples were prepared in a thin film format by evaporative deposition techniques. FT-IR methods were calibrated using a set of samples with a range of known wt % ethylene content. For ethylene-1-octene copolymers, the wt % octene in the copolymer was determined via measurement of the methyl deformation band at about 1,375 cm.sup.−1. The peak height of this band was normalized by the combination and overtone band at ˜4321 cm-1, which corrects for path length differences.

(320) For ethylene-octene copolymers, the wt % ethylene is determined via measurement of the methylene rocking band (about 770 cm.sup.−1 to about 700 cm.sup.−1). The peak area of this band is normalized by sum of the band areas of the combination and overtone bands in the range of about 4,500 cm.sup.−1 to about 4000 cm.sup.−1. For samples with composition outside the calibration range, the wt % ethylene was determined by .sup.1H NMR spectroscopy or estimated from the polymer Tm.

(321) .sup.1H NMR data were collected at 120° C. in a 5 mm probe using a spectrometer with a .sup.1H frequency of 500 MHz. Data was recorded using a maximum pulse width of 45°, 5 seconds between pulses and signal averaging 120 transients. Spectral signals were integrated.

(322) Table 1 provides the reaction conditions for ethylene octene copolymerization (EO) using DMAH-PFPB or MAO.

(324) Tables 2 and 3 provide catalyst activity and polymer properties for ethylene-octene copolymerization (EO) using DMAH-PFPB or MAO. Experiments 1-20 utilized the catalyst represented by Formula (VII) containing zirconium (Zr-VII catalyst) and Experiments 21-39 utilized the catalyst represented by Formula (VII) containing hafnium (Hf-VII catalyst). Experiments 1-10 and 21-29 included the scavenger TNOAL at a concentration of 0.5 μmol, while the remainder of the experiments did not contain a scavenger. The catalytic activities shown in Experiments 1-20 (Zr-VII catalyst) were in a range from about 25 kg/mmol/hr to 165 kg/mmol/hr. The catalytic activities shown in Experiments 21-39 (Hf-VII catalyst) were in a range from about 104 kg/mmol/hr to 260 kg/mmol/hr. For comparing the overall catalytic activity, the Hf-VII catalyst outperformed the Zr-VII catalyst.

(325) Both the Zr-VII catalyst and the Hf-VII catalyst provide particularly high molecular weight polymers (289 Kg/mol to 657 Kg/mol with Zr-VII; 168 Kg/mol to 342 Kg/mol with Hf-VII) with narrow PDI (1.4 to 2.4) and high comonomer content (12.9 wt % to 19.5 wt %). For example, as shown in Tables 2 and 3, Example 11, the polymer obtained using Zr-VII as the catalyst in presence of MAO at 80° C. and 95 psi has a comonomer content (C.sub.8 wt %) of 19.5 wt %.

(326) The results obtained using the novel catalysts provide promising advantages for processability of the polymer itself and the polymer in a composition.

(329) Overall, the present disclosure provides catalyst compounds including a nonsymmetric bridged amine bis(phenolate), catalyst systems including such, and uses thereof. Catalyst compounds, catalyst systems, and processes of the present disclosure can provide high comonomer content and high molecular weight polymers having narrow PDI values, contributing to good processability for the polymer itself and for the polymer used in a composition.

(330) The phrases, unless otherwise specified, “consists essentially of” and “consisting essentially of” do not exclude the presence of other steps, elements, or materials, whether or not, specifically mentioned in this specification, so long as such steps, elements, or materials, do not affect the basic and novel characteristics of the present disclosure, additionally, they do not exclude impurities and variances normally associated with the elements and materials used.

(331) For the sake of brevity, only certain ranges are explicitly disclosed herein. However, ranges from any lower limit may be combined with any upper limit to recite a range not explicitly recited, as well as, ranges from any lower limit may be combined with any other lower limit to recite a range not explicitly recited, in the same way, ranges from any upper limit may be combined with any other upper limit to recite a range not explicitly recited. Additionally, within a range includes every point or individual value between its end points even though not explicitly recited. Thus, every point or individual value may serve as its own lower or upper limit combined with any other point or individual value or any other lower or upper limit, to recite a range not explicitly recited.

(332) All documents described herein are incorporated by reference herein, including any priority documents and/or testing procedures to the extent they are not inconsistent with this text. As is apparent from the foregoing general description and the specific embodiments, while forms of the present disclosure have been illustrated and described, various modifications can be made without departing from the spirit and scope of the present disclosure. Accordingly, it is not intended that the present disclosure be limited thereby. Likewise, the term “comprising” is considered synonymous with the term “including.” Likewise whenever a composition, an element or a group of elements is preceded with the transitional phrase “comprising,” it is understood that we also contemplate the same composition or group of elements with transitional phrases “consisting essentially of,” “consisting of,” “selected from the group of consisting of,” or “is” preceding the recitation of the composition, element, or elements and vice versa.

(333) While the present disclosure has been described with respect to a number of embodiments and examples, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope and spirit of the present disclosure.
