Gamma-ray-induced graft copolymerization of butadiene with vinyl monomers onto polyvinyl chloride was attempted to improve the physical properties of polyvinyl chloride. The Izod impact strength was increased from 2 kg cm/cm/sup 2/ to more than 100 kg cm/cm/sup 2/ by grafting ca. 10% butadiene. But the tensile strength and melt flow were decreased by the grafting. The electron micrograph showed that the mass of polybutadiene in the graft copolymer had a convenient diameter (0.1 to 1 ..mu..) for absorbing the impact energy. The weatherability of polyvinyl chloride grafted with butadiene was improved by cografting of butadiene with acrylates and methacrylates which had long side chains. 7 figures, 3 tables.
