ABSTRACT:
Novel high impact plastics are prepared by the inclusion of 2 to 30 weight percent of bromobutyl rubber in polymers of styrene and styrene-acrylonitrile and the grafting of said polymers onto said rubber. The graft copolymers are obtained by polymerizing the monomers of styrene or styrene-acrylonitrile in the presence of the bromobutyl rubber, which is preferably precrosslinked.
