摘要
An improved process for grafting vinyl chloride onto ethylene-vinyl acetate or ethylene-alkyl acrylate copolymers in the gel phase in the presence of radical formers soluble in the monomer wherein the ethylene-vinyl acetate or ethylene-alkyl acrylate copolymer is in powder form and a combination of at least two initiators having different decomposition temperatures are employed during the grafting, the resultant grafted copolymer and the use of the same as an impact strength improving component or polyvinyl chloride or vinyl chloride copolymers.
