ABSTRACT OF THE DISCLOSURE There is disclosed a polycarbonate resin composition comprising (A) 100 parts by weight of a polycarbonate resin, and (B) 1 to 80 parts by weight of an acrylic ester graft copolymer comprising grafting, on 100 parts by weight of an acrylic ester copolymer which comprises copolymerizing (i) 100 parts by weight of at least an acrylic ester monomer having 1 to 16 carbon atoms and (ii) 0.1 to 5 parts by weight of a polyfunctional allyl ester monomer and/or a polyfunctional methallyl ester monomer having a benzene ring as a skeleton, (iii) 15 to 100 parts by weight of at least a vinyl monomer selected from the group consisting of a methacrylic ester, an aromatic monovinyl compound and a vinyl cyanide compound and an acrylic ester in a proportion of 0 to 20% by weight to the vinyl monomer and (iv) 0.1 to 5 parts by weight of a polyfunctional allyl ester monomer and/or a polyfunctional methallylester monomer having a benzene ring as a skeleton. Furthermore, there is disclosed a polycarbonate resin composition comprising incorporating 4 to 150 parts by weight of an aromatic polyester resin (C) into the components (A) and (B). The aforementioned composition is excellent in low temperature impact resistance, thermal stability, solvent resistance and the like and useful as a molding material.
