The present invention provides polymer blends that can be used in a multilayer structure and to multilayer structures comprising one or more layers formed from such blends. In one aspect, a polymer blend comprises an ionomer of a copolymer comprising ethylene and at least one of acrylic acid and methacrylic acid having a melt index (I.sub.2) of 1 to 60 g/10 minutes, wherein the total amount of ionomer comprises 50 to 99 weight percent of the blend based on the total weight of the blend, and a polyolefin having a density of 0.870 g/cm.sup.3 or more and having a melt index (I.sub.2) of 20 g/10 minutes or less, wherein the polyolefin comprises 1 to 50 weight percent of the blend based on the total weight of the blend, wherein the polymer blend meets the following equation: 3.5<2.76-60*I.sub.2(PO+308*RVR+0.023*A<4.5 wherein I.sub.2(PO) is the melt index (I.sub.2) of the polyolefin, RVR is the relative viscosity ratio of the polyolefin to the ionomer (I.sub.2(PO)/I.sub.2(ionomer)), and A is the weight percent of ionomer in the polymer blend based on the total weight of the blend.
Utilization of Fine Mineral Matter in the Conversion of Non-Biodegradable Plastic and in Remediation of Soils Polluted with Non-Biodegradable Plastic
The disclosed invention describes a novel approach to the utilization of the fine mineral matter derived from coal and/or coal refuse (a by-product of coal refining) to convert a non-biodegradable plastic into a biodegradable plastic. The fine mineral matter could also be based on volcanic basalt, glacial rock dust deposits, iron potassium silicate and other sea shore mined deposits. The conversion of the non-biodegradable plastic into biodegradable plastic in soil further increases nutrients availability in soil with the transition metals released as a result of biodegradation of the biodegradable plastic.
SACRIFICIAL MICROSPHERES
A polymeric material can be deposited or coated on a surface of a hollow microsphere to produce a sacrificial microsphere. Sacrificial microspheres can provide a cost-effective way to produce lightweight plastics and composites.
Carbon fiber bundle for resin reinforcement, and method for manufacturing carbon fiber bundle for resin reinforcement, carbon-fiber-reinforced thermoplastic resin composition, and molded body
A carbon fiber bundle for resin reinforcement, wherein there are adhered by 0.1-5.0 mass % to a carbon fiber bundle in which multiple lengths of filament are bundled, a mixture created by mixing an organic polymer (A) having a mass-average molecular weight of 10000 or more and an organic compound (B) the thermal reduction rate specified in claim 1 of which is 5 mass % or more or an organic compound (B) the thermal reduction rate specified in claim 2 of which is 0.8 mass % or more, the amount of the organic polymer (A) adhered being 0.1 mass % or more.
AQUEOUS DISPERSION OF POLYALKENE SUPRAMOLECULAR POLYMER AND ITS USE IN COSMETICS
The present invention relates to an aqueous dispersion of polyalkene supramolecular polymer with a surfactant system chosen from an anionic surfactant, a cationic surfactant and a non-ionic surfactant. The invention also relates to a cosmetic composition comprising such a dispersion. Use for caring for and making up keratin materials.
PRECIPITATION OF POLYETHER BLOCK AMIDE AND THERMOPLASTIC POLYETHYLENE TO ENHANCE OPERATIONAL WINDOW FOR THREE DIMENSIONAL PRINTING
A polymer material suitable for three-dimensional printing that may include at least one of polyether block amide, thermoplastic polyeurothane, and thermoplastic olefin. The polymer is formed through chemical precipitation forming a precipitated pulverulent polymer which possesses increased operating window characteristics selected from the group consisting at least one of a wider than typical range between and among the melting and recrystallization temperatures, a larger enthalpy upon melting, and a low volumetric change during recrystallization.
ADDITION OF BIODEGRADABILITY LENDING ADDITIVES TO PLASTIC MATERIALS
Described herein are methods for rendering biodegradable a plastic material that is not itself biodegradable, by blending the plastic material with a carbohydrate-based polymeric material that is formed from a) one or more starches and a plasticizer (e.g., glycerin), b) an additive known in the art as an OXO material and/or an additive that interacts with microbes that contribute to biodegradation of the non-biodegradable material. The carbohydrate-based polymeric material is less crystalline than the non-biodegradable materials, e.g., being substantially amorphous, and having a crystallinity of no more than 20%. When tested under conditions causing biodegradation, the blend biodegrades to an extent greater than the content of the carbohydrate-based polymer.
PELLETIZATION OF A POLYMER STABILIZER MIXTURE
The invention relates to a method for manufacturing a pellet in a pellet mill, which method comprises the steps of (A) pressing a mixture for compaction by a roller through a nozzle to obtain a strand, and (B) comminuting the strand to obtain the pellet, wherein the mixture for compaction comprises (i) 87 to 97 wt. % of a polymer stabilizer mixture polymer stabilizer mixture, which comprises the polymer stabilizers (i-1) 62 to 72 wt. % of tris(2,4-ditert-butylphenyl) phosphite (CAS-No. 31570-04-4), (i-2) 28 to 38 wt. % of tetrakis-[3-(3,5-ditert-butyl-4-hydroxy-phenyl)-propionyloxymethyl]me-thane (CAS-No. 6683-19-8), and wt. % of the polymer stabilizers (i-1) and (i-2) are based on the weight of the polymer stabilizer mixture, and (ii) 3 to 13 wt. % of a processing aid, which is a polyethylene and which possesses a weight average molecular weight above 2500 Da and below 16000 Da. The pellet is useful for a dust-free handling of its polymer stabilizer mixture at a manufacturing of a stabilized polymer. Furthermore, a method for stabilizing a polymer, which is a polyolefin, a polystyrene or a mixture thereof, is disclosed, which comprises the dosing of the pellet to the polymer.
MOLDED BODY, METHOD OF PRODUCING THE SAME, AND RECYCLING METHOD
A molded body includes a non-foamed design layer, a foamed intermediate layer, and a non-foamed back layer, laminated in this order and formed of a first, second, and third resin compositions, respectively. The first, second, and third resin compositions contain a polyolefin as a main component. The first resin composition is an impact-resistant resin composition including a polyolefin, a polyamide, and a polyolefin-based modified elastomer having a reactive group reactive with the polyamide. A method of producing the molded body includes disposing a first support layer to serve as the design layer and a third support layer to serve as the back layer so as to be spaced apart from and face each other, interposing the second resin composition provided with foamability in a gap between the first and third support layers, and forming the intermediate layer by expanding the gap while causing the second resin composition to foam.
