A composition comprises a vinyl chloride homopolymer or copolymer having 55 to 85% of its chlorine atoms arranged syndiotactically and an ethylene-vinyl acetate copolymer. The composition may also contain stabilizers, lubricants and other high polymers, e.g. polyethylene, polypropylene, polyisobutylene, polyvinyl acetate, chlorinated polyvinyl chloride, polyacrylonitrile, or a polyvinyl ether. The vinyl chloride copolymer may be a copolymer with ethylene, propylene, vinyl acetate, or dichlor-ethylene. |
