A polymeric blend containing (1) copolymer of lactone with conjugated diene or monovinylarene or both conjugated diene and monovinylarene, (2) acrylic ester polymer and (3) coumarone-indene resin.

Nucleating agents have been discovered which enable molded articles to be prepared with smooth glossy surfaces from blends of polyethylene terephthalate and polybutylene terephthalate in the "wet state", i.e., without the resin having been subjected to a predrying stage. The present invention is directed to polyalkylene terephthalate resin compositions. Specifically, it is directed to undried blends of polyethylene terephthalate and polybutylene terephthalate resins with nucleating agents which ...

Polymers containing a high percentage of vinyl alcohol units may be blended with copolymers of alkyl methacrylates and unsaturated organic acids and processed into sheet, film, fiber and other objects which exhibit an useful balance of barrier and strength properties.

A polyethylene composition comprising: (a) about 1 to about 30 weight percent of a branched polyethylene resin, wherein said resin is produced by the high pressure, free radical, polymerization process, and wherein said resin has a density from about 0.91 to about 0.93 grams per cubic centimeter, and wherein said resin has a melt index less than 6 grams per 10 minutes; and (b) about 99 to about 70 weight percent of a linear polyethylene resin, wherein said resin is produced by the low pressure, ...

Polymers containing a high percentage of vinyl alcohol units may be melt-blended with copolymers of alkyl(meth)acrylates and unsaturated organic acids. Flexible films are formed when one of the methacrylic monomers is a monoterminally (meth)acrylated oligomer or polymer of ethylene glycol or propylene glycol.

A transparent blend composition comprising a methyl methacrylate-tribromophenyl maleimide copolymer and polycarbonate, the weight percent ratio of the copolymer to the polycarbonate being about 1:99 to about 99:1.

A composition of matter comprising: (a) 10 to 80 weight percent inclusive of a low molecular weight polyethylene resin having a density of at least 0.94 grams per cubic centimeter, a melt index greater than 25 grams per 10 minutes, and a heterogeneity index between 2 and 12 inclusive; and (b) 20 to 90 weight percent inclusive of a high molecular weight ethylene copolymer having a density less than 0.955 grams per cubic centimeter, a high load melt index between 2 and 10 grams per 10 minutes incl...

A blended polymer composition that comprises: (a) from about 10 weight percent to about 40 weight percent of an ethylene-vinyl acetate copolymer resin; and (b) from about 60 weight percent to about 90 weight percent of a linear ethylene copolymer resin; wherein said weight percents are based on the weight of said polymer composition. A blended polymer composition that comprises: (a) from about 10 weight percent to about 40 weight percent of an ethylene-vinyl acetate copolymer resin; (b) from abo...

Incorporation of a thermoplastic polyurethane and at least one thermoplastic crystalline polymer selected from nylon 6, nylon 612, polypropylene, and polyalkylene terephthalates containing at least one ethylene copolymer into polyacetal polymer results in blends characterized as having improved toughness, or impact strength, and improved elongation over that of a comparable blend of polyacetal and at least one of said crystalline polymers alone.

Halide polymer such as polyvinylchloride and polyamide are melt blendable when the melt blending is carried out at a temperature of no greater than about 220.degree. C. and the polyamide has a processing temperature no greater than the temperature of melt blending and the melt blend also incorporates a carboxyl and/or CO-functional ethylene polymer which compatibilizes the PVC and polyamide one with the other.
