Abstract: A vinyl polymer composition comprising a vinyl polymer, a heat stabilizer, an impact modifier and an ethylene-vinyl acetate copolymer having improved impact resistance is disclosed. A process for forming the vinyl polymer composition is also set forth. In this process an improved processing aid, an ethylene-vinyl acetate copolymer, is blended with a vinyl polymer, a heat stabilizer and an impact modifier.

Abstract: A container is provided with a coating having a frosty appearance comprising an olefin-vinyl ester copolymer the exterior surface of which is hydrolyzed following application of the coating to the exterior surface container. Surface hydrolysis of the olefin-vinyl ester coating significantly improves container-to-container lubricity without appreciably affecting the mechanical properties of the coating.

Abstract: Polymer blends of improved impact strength are prepared by mixing polyvinyl chloride with an impact strength-increasing amount of an vinyl acetate-ethylene copolymer which has been pre-blended with an ultrafine particle size inert inorganic filler.

Abstract: Ultraviolet radiation and impact resistant thermoplastic blends are provided which comprise:(a) a polymer triblend comprising:i. from about 5 parts per hundred (pph) to about 40 pph of at least one resin selected from the group consisting of a copolymer of ethylene and vinyl acetate containing from about 25 percent to about 75 percent vinyl acetate and a terpolymer of ethylene, vinyl acetate and the theoretical monomer vinyl alcohol containing from about 20 percent to about 80 percent ethylene, from about 18 percent to about 60 percent vinyl acetate and from about 2 percent to about 20 percent vinyl alcohol;ii. from about 50 pph to about 95 pph of a copolymer of styrene and acrylonitrile containing from about 15 percent to about 40 percent acrylonitrile;iii. from about 0.1 pph to about 40 pph of a chlorine-containing polymer such as chlorinated polyethylene or polyvinylchloride; and(b) from about 2 to about 40 pph titania particulate.

Abstract: Sulfur dioxide-ethylene-vinyl ester terpolymers exhibiting improved thermal stability are prepared by substantially uniformly incorporating therein a thermal stability-imparting amount of at least one inorganic oxygen-containing metal compound in which the metal is an alkali metal, alkaline earth metal or zinc.
