Abstract
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.
