Abstract

Polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile and copolymers of butadiene and styrene are halogenated by being subjected to a halogenating agent while exposed to a field of high energy radiation. The product is both halogenated and cross-linked. Specifications 784,923 and 834,905 are referred to.ALSO:Polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile and copolymers of butadiene and styrene are halogenated by being subject to a halogenating agent while exposed to a field of high-energy radiation.
