Abstract
PURPOSE: To obtain titled resin having excellent heat-distorsion resistance, etc., by graft-polymerizing a vinyl chloride type monomer in the presence of an ethylene/vinyl acetate copolymer, a polymerization initiator, etc., and then chlorinating the graft copolymer.
CONSTITUTION: (A) Ethylene is copolymerized with (B) vinyl acetate or an alkyl (C1WC18) acrylate so that the resulting copolymer (hereinafter abbreviated as EVA) has a component B content of about 5W80wt%. Then, vinyl chloride or a mixture containing vinyl chloride and a monomer copolymerizable therewith is graft- polymerized in the presence of EVA, an aqueous medium, an oil-soluble polymerization initiator and a dispersant, to form an EVA/vinyl chloride graft copolymer having an EVA content of about 2W50wt%. Next, titled resin is obtained by chlorinating the graft copolymer so as to obtain a degree of chlorination of 5W 50wt%.
