A polycarbonate resin composition comprising (A) 20 to 90% by weight of a polycarbonate resin, (B) 5 to 70% by weight of an aromatic polyester resin, (C) 1 to 15% by weight of an isobutylene copolymer rubber composed of a major proportion of isobutylene and a minor proportion of isoprene, (D) 1 to 20% by weight of an elastomeric acrylic graft copolymer resin composed of, as a trunk polymer, a crosslinked acrylic copolymer containing not less than 3% by weight of butadiene as a comonomer and being free from ethylene and grafted thereto, at least one grafting monomer selected from the group consisting of styrene, alkyl acrylates and alkyl methacrylates, and (E) 0 to 15% by weight of an olefin resin derived from an olefin having 2 to 6 carbon atoms; wherein the weight ratio of [resin (A)+resin (B)]/[rubber (C)+resin (D)] is from 2 to 20, and if the resin (E) is present, the weight ratio of resin (B)/[rubber (C)+resin (D)+resin (E)] is from 1 to 5. |
