Smith, W V

Certain vinyl chloride copolymers can be crosslinked by small doses of ionizing radiation, in contrast to the behavior of polyvinyl chloride and its other copolyrners. These copolymers include the high-molecular-weight resinous copolymers of vinyl chloride with 10 to 40% of the following monomersv dialkyl maleates and fumarates in which each alkyl group contains 4 or more C atoms, vinyl esters of fatty acids containing 3 or more C atoms, vinyl alkyl ethers in which the alkyl group contains 18 or more C atoms, alkyl acrylates, and alkyl methacrylates in which the alkyl group contains 3 or more C atoms. The inclusion of a reinforcing filler, e.g., carbon black or silica, renders the irradiated copolymer especially strong at high temperatures. (D.L.C.) (C L fr Pu ro-~
