PURPOSE:The titled composition having extremely improved impact resistance in a cold atmosphere and gasoline resistance, obtained by adding both butyl rubber and an acrylic elastic material to polycarbonate. CONSTITUTION:(A) 100pts.wt. polycarbonate is blended with (B) 0.5-10pts.wt., preferably 1-5pts.wt. butyl rubber and (C) 0.5-10pts.wt., preferably 1-5pts.wt. acrylic elastic material. Synthetic rubber having a low degree of unsaturation obtained by copolymerizing isobutylene with 1-7wt% isoprene in the presence of a metal halide compound at about -100 deg.C is used as the component B. |
