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.

Vinyl polymer composition and process for making same

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.

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.
