摘要： A novel resin composition having high transparency and high impact strength comprises (I) 97 to 99.99 percent by weight of a resin composed of (A) 10 parts by weight of polybutadiene or a styrene-butadiene rubber containing at least 60 percent by weight of butadiene which has a weight average particle diameter of 0.20 to 0.35 Mu with a particle diameter distribution in the range of 0.05 to 1.5 Mu and a degree of swelling of at least 10, and (B) 15 to 190 parts by weight of a terpolymer of a monomer mixture comprising 30 to 65 percent by weight of styrene, 15 to 68 percent by weight of methyl methacrylate and 2 to 20 percent by weight of acrylonitrile (said resin may be a mixture of (A) and (B) or may be a graft-copolymer of (B) and (A)) and (II) 0.01 to 3 percent by weight of a polyorganosiloxane having a viscosity of 10 to 30 centistokes. From such composition, a transparent and impact resistant molded article can be produced regardless of the molding conditions. Further, the composition, when used in combination with a vinyl chloride polymer, can give an impact resistant resin which is transparent or translucent and has a self-extinguishing property.
