Graft polymers of vinyl chloride on unsaturated olefinic elastomers and process for the preparation thereof

Impact resistant compositions comprising crude graft polymers of vinyl chloride on unsaturated olefinic elastomers, said elastomers being copolymers of ethylene, an alpha -olefin and a diene or a polyene, are prepared by graft polymerizing vinyl chloride onto an olefinic elastomer. The graft polymer...

More Information
Summary:Impact resistant compositions comprising crude graft polymers of vinyl chloride on unsaturated olefinic elastomers, said elastomers being copolymers of ethylene, an alpha -olefin and a diene or a polyene, are prepared by graft polymerizing vinyl chloride onto an olefinic elastomer. The graft polymerization is discontinued before 70% of the vinyl chloride has been polymerized.
