The present invention provides a resin composition which is excellent in moisture and heat resistance, thermal stability, rigidity, surface impact properties and chemical resistance. The resin composition includes, based on a total of 100 parts by weight consisting of (A) 30 to 99 parts by weight of a resin (component A), which is composed of 10 to 100 wt % of a polycarbonate-polydiorganosiloxane copolymer resin (component A1) and 0 to 90 wt % of an aromatic polycarbonate resin (component A2), and (B) 1 to 70 parts by weight of a polyester resin (component B), (C) 10 to 50 parts by weight of a filler (component C) which is surface-treated with a silane coupling agent having an alkyl group, wherein the content of rubber-like polymer is 3 parts by weight or less.

A method of carrying out a metathesis reaction includes the combination of at least one alkene or non conjugated diene with a Ruthenium-based catalyst with an cyclic(alkyl)(amino)carbene ligand to form a reaction mixture and heating the reaction mixture to a temperature of 100 C. or greater. The reaction can be an ADMET, ROMP, a metathesis ring-closure or an olefin exchange reaction.

The present invention relates to a chrome compound composed of non-coordinating anions and a trivalent chrome cation, a reactant of the chrome compound and a bidentate ligand, an ethylene oligomerization reaction catalyst system using the chrome compound and the reactant, and a method for preparing an ethylene oligomer using the catalyst system. Through the above conformation, the present invention can selectively produce 1-hexene and 1-octene with high activity while omitting the use of methylaluminoxane (MAO), and can provide an ethylene oligomerization process more suitable for mass production.

A highly efficient, Z-selective ring-closing metathesis system for the formation of macrocycles using a stereoretentive, ruthenium-based catalyst supported by a dithiolate ligand is reported. This catalyst is demonstrated to be remarkably active as observed in initiation experiments showing complete catalyst initiation at 20 C. within 10 min. Using easily accessible diene starting materials bearing a Z-olefin moiety, macrocyclization reactions generated products with significantly higher Z-selectivity in appreciably shorter reaction times, in higher yield, and with much lower catalyst loadings than in previously reported systems. Macrocyclic lactones ranging in size from twelve-membered to seventeen-membered rings are synthesized in moderate to high yields (68-79% yield) with excellent Z-selectivity (95%-99% Z).

An alkylation process is described. The alkylation process includes contacting a feed comprising a paraffin or an aromatic with an olefin feed in the presence of a liquid Lewis acid catalyst in an alkylation reaction zone under alkylation conditions to form a reaction mixture comprising alkylation products and the liquid Lewis acid catalyst. The liquid Lewis acid catalyst is the liquid reaction product of a donor molecule and a metal halide. The alkylation products are separated from the liquid Lewis acid catalyst and recovered.

A process for selectively producing 1-butene comprises combining at least one antifouling agent and at least one aluminum alkyl compound to form an antifouling feed stream, wherein bringing the antifouling agent into contact with the aluminum alkyl compound forms at least one antifouling agent co-catalyst in a first step. The antifouling agent co-catalyst may comprise a structure comprising a central aluminum molecule bound to an R1 group, an R2 group, and an R3 group. The process further comprises feeding the antifouling feed stream, a catalyst comprising at least one titanate compound, and ethylene into a reactor dimerize ethylene in a second step. The catalyst is fed as a stream separated from the antifouling feed stream. The feeds may be varied in real-time to adjust a ratio of the formed antifouling agent co-catalyst and residual aluminum alkyl compound or antifouling agent in the antifouling feed stream.

In one aspect, phosphine compounds comprising three adamantyl moieties (PAd.sub.3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd.sub.3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.

In one or more embodiments, the present invention is directed to a novel method for synthesizing Mg(BHT).sub.2(THF).sub.2 catalyst, which has several advantages over previous methods. Dry toluene or pentane are not required for synthesizing the catalyst, and the reaction is done in a bulk solution of BHT and THF. Further, because the Mg(BHT).sub.2(THF).sub.2 is made in a one-step (one-pot) synthesis, the time required for synthesizing and drying the catalyst is reduced. Using the new method of the present invention, the Mg(BHT).sub.2(THF).sub.2 is pure after removing excess THF, thereby eliminating the need for washes and recrystallization.

A method of carrying out a metathesis reaction includes the combination of at least one alkene or non conjugated diene with a Ruthenium-based catalyst with an cyclic(alkyl)(amino)carbene ligand to form a reaction mixture and heating the reaction mixture to a temperature of 100 C. or greater. The reaction can be an ADMET, ROMP, a metathesis ring-closure or an olefin exchange reaction.

A method for producing polyurethanes containing alkoxysilane groups comprises the step of reacting a compound containing at least one NCO group with a compound containing at least one Zerewitinoff-active H atom in the presence of a catalyst component, wherein the compound containing at least one NCO group and/or the compound containing at least one Zerewitinoff-active H atom contain at least one alkoxysilane group, to obtain a polyurethane containing alkoxysilane groups. The invention also relates to a polymer containing alkoxysilane groups, a method for producing a curable polymer, a curable polymer, a cured polymer, and the use thereof. The polymers contain a complex of a lanthanide with at least one beta-diketonate ligand, preferably Yb(acac).sub.3, and are free from organic tin compounds.
