ABSTRACT:
A process for preparing a vinyl chloride copolymer which comprises polymerizing a vinyl chloride monomer or a mixture of a major proportion of a vinyl chloride monomer with a minor proportion of a copolymerizable monomer and at least one crosslinking agent selected from polyhydric alcohol diglycidyl ether diacrylates and dimethacrylates. The crosslinking agent is added to the reaction system after polymerization of the vinyl chloride monomer or the mixture proceeds to a certain extent. By this, the resultant copolymer has good processability and good mechanical and electric characteristics.
