Abstract

PURPOSE: An ethylene vinyl acetate-vinyl chloride graft copolymer capable of giving resin compositions having improved processability and practical impact strength, with specific contents of ethylene-vinyl acetate copolymer and vinyl acetate.
CONSTITUTION: A polymer, prepared by grafting vinyl chloride (VC) or its mixture with copolymerizable monomers onto ethylene-vinyl acetate copolymer (EVA), with an EVA content of 25W55 wt.%, preferably 30W40 wt.%, and a vinyl acetate content in the EVA of 15W30 wt.%, preferably 18W28 wt.%. VC monomer is polymerized in the presence of an aqueous medium, a dispersing agent, an oil-soluble initiator, and EVA at a weight ratio of VC to EVA of 1:1W3.5:1, and the weight ratio of (the charged monomer and its polymer) to the EVA is maintained in said range until 20 wt.% of the initially charged VC is polymerized.
