IMPROVEMENTS IN VINYL CHLORIDE COPOLYMERS
Patent

OSTI ID:4013559
A method is described for improving the physical properties of vinyl chloride copolymers by radioinduced crosslinking. The method consists of shaping to a desired form a resinous copolymer composition of 95 to 50% by weight of vinyl chloride and correspondingly 5 to 50% of one or more monomers copolymerizable from dialkyl maleates (4 to 20 carbons), vinyl esters of fatty acids (3 to 20 carbons), vinyl alkyl ethers (18 to 30 carbons), alkyl acrylates (1 to 20 carbons), or alkyl methacrylates (3 to 20 carbons). The formed composition is then subjected, in the absence of any ethylenically unsaturated plastifying agent, to a dosage of ionizing radiation of 5 to 50 watt-hours per pound. The copolymer is cross-linked and the physical properties are improved. A sintilar method is discussed for vinyl chloride terpolymers. (N.W.R.)
