    摘要： When the impact resistant resin composition comprising a graft polymer in which an aromatic alkenyl compound and an alkenyl cyanide compound are grafted on a rubbery polymer, and a matrix consisting essentially of an aromatic alkenyl compound-alkenyl cyanide compound copolymer satisfies the following conditions, the composition has an improved vacuum formability and the molded articles obtained by vacuum-forming the same have smaller variations in thickness at any given area and there is a smaller reduction of strength due to contact with foamed polyurethane:(1) the proportion of the rubbery polymer in said impact resistant resin composition is 10-30% by weight,(2) the graft polymer has a degree of grafting of 70-120% by weight,(3) the matrix has an intrinsic viscosity of 0.55-0.80 dl/g as measured at 30.degree. C. in methyl ethyl ketone, and(4) the weight ratio of the aromatic alkenyl compound to the alkenyl cyanide compound in the impact resistant resin composition is in the range of 2.0-2.8. When said resin composition contains further 0.01-2.0% by weight of a diorganopolysiloxane having a viscosity of 5-100,000 centistokes at 25.degree. C. and/or 0.1-3% by weight of a metal salt of a fatty acid, its ability to maintain the strength upon contact with foamed polyurethane is enhanced.
