Abstract
A vinyl chloride copolymer is produced by copolymerizing vinyl chloride monomer or a monomer mixture comoposed of vinyl chloride monomer and copolymerizable monomer, with one or more than one kind of cross-linking agent selected from polyhydric alcohol diglycidyl ether diacrylate and dimethacrylate. The vinyl chloride copolymer has good moldability and can be made into moldings having good matte finish surface and also good permanent compression set resistance, creep resistance, heat resistance, and electrical properties.
