Zusammenfassung:	PURPOSE:To provide a method for production of a vinylchloride-based resin excellent in impact resistance. CONSTITUTION:The production process of this vinylchloride-based resin comprises adding and impregnating beforehand an oil soluble polymerization initiator to 1-30wt.% acryl-based copolymer latex obtained by copolymerizing (A) 100 pts.wt. acryl-based monomer containing an alkyl(metha)acrylate of which homopolymer has -20 deg.C glass transition temperature as a major component with (B) 0.1-10 pts.wt. multi-functional monomer, and then graft- copolymerizing 7099 wt.% vinylchloride therewith by a suspension polymerization.
