-1- The present invention is directed to a thermoplastic resin composition comprising (A) 5 to 50 parts by weight of a saturated polyester resin, (B) 10 to 70 parts by weight of a graft polymer obtainable by polymerizing an aromatic vinyl compound and an unsaturated nitrile in the presence of a conjugated dime base rubber, (C) 10 to 70 parts by weight of an .alpha.-alkylstyrene- unsaturated nitrile copolymer comprising 50 to 85 % by weight of the .alpha.-alkylstyrene and 50 to 15 % by weight of the unsaturated nitrile, provided that the total amount of the components (A), (B) and (C) is 100 parts by weight, wherein the content of the conjugated dime base rubber in the composition is from 5 to 30 % by weight. The composition provides a molded article having improved properties, e.g. chemical resistance, impact resistance, flexural modulus, heat resistance and dimensional stability.
