Abstract Of The Disclosure Vinylchloride resins such as polyvinylchloride, copolymers of vinylchloride and vinyl acetate and copolymers of vinylchloride and vinylidene chloride are dehydrochlorinated in water at 150 to 180°C to provide a dehydrochlorinated vinylchloride resin which can be graft copolymerized with one or more copolymerizable monomers containing polymerizable ethylenically unsaturated double bonds. Grafted copolymers in which the grafting monomer is butyl acrylate and the like provide an internally plasticized vinylchloride resin.
