A comparison of some physical properties of polyethylene–styrene graft copolymers prepared by the trapped free radical method and polyethylene–polystyrene blends

Abstract The preparation and properties of polyethylene–styrene graft copolymers using trapped free radicals produced by gamma rays has been reported. When polystyrene branches are attached to the polyethylene chain there is reinforcement of the properties of polyethylene, whereas the corresponding physical blend of polystyrene and polyethylene has lowered physical properties.
