PROBLEM TO BE SOLVED: To obtain a polycarbonate resin composition excellent in appearance, strength, rigidity and heat resistance, and also in flowability and moldability by blending an aromatic polycarbonate resin, an aromatic polycarbonate oligomer, a rubber-polyester block copolymer and an inorganic filler. SOLUTION: This composition is obtained by blending 45-90wt.% aromatic polycarbonate resin comprising an optionally branched thermoplastic polycarbonate polymer obtained by reacting an aromatic dihydroxy compound or its mixture with a small amount of a polyhydroxy compound with phosgene or a carbonic diester; 2-15wt.% aromatic polycarbonate oligomer obtained by reacting bisphenol A with phosgene or a carbonic diester by using a molecular weight modifier; 1-10wt.% rubber-polyester block copolymer comprising an aliphatic diene rubber having polyester block terminal (s); and 4-40wt.% inorganic filler comprising, e.g. glass fibers or carbon fibers. |
