Abstract

PURPOSE: To enhance workability, wear resistance, etc., by the graft copolymerization of vinyl chloride and a monomer mixture copolymerizable with it, with an ethylene-vinyl acetate copolymer containing a specified proportion of vinyl acetate, in a specified ratio, in the presence of a crosslinkable monomer.
CONSTITUTION: Vinyl chloride and a monomer mixture copolymerizable with it (hereinafter referred to as vinyl chloride monomers), are copolymerized with an ethylene-vinyl chloride copolymer containing 50W80wt% vinyl acetate (EVA), in a weight ratio of vinyl chloride monomers/EVA of 0.5/1W4/1, in the presence of an aqueous medium, an oil-soluble polymerization initiator and a crosslinkable monomer (ethylene glycol diacrylate, etc.), to prepare an EVA-vinyl chloride copolymer containing 20W80wt% of EVA. 1W8wt%, based on vinyl chloride monomers, of a crosslinkable monomer is used. The polymerization is ceased before completion of the polymerization, and an excess of vinyl chloride monomers is removed from the system, to obtain a desired graft copolymer. Thus oil resistance, cold resistance, heat deformation properties, etc. are enhanced.
