摘要: The present invention is specifically directed to improved polyvinyl chloride compositions having excellent impact strength. In particular, the resistant composition comprises a vinyl polymer and 2-8 parts of an modifier comprising at least one ethylene/alpha-olefin copolymer chlorinated olefin per 100 polymer. Preferably less than 1 part ratio said total 25%.
