THERMOPLASTIC POLYESTER RESIN COMPOSITION AND MOLDED ARTICLE

摘要

A molded article of an aromatic polyester block copolymer resin which is excellent in hydrolytic resistance, heat resistance, and yellowing resistance. The thermoplastic polyester resin composition comprises: 100 parts by weight of a polyester block copolymer (A) which is obtained by reacting a thermoplastic aromatic polyester with a lactone and has a terminal carboxy group content less than 5 mg-KOH/g; 0.05 to 5 parts by weight of a polycarbodiimide compound (B); 0.05 to 5 parts by weight of an epoxy compound (C) having a functionality of 2 or higher; 0.01 to 0.5 parts by weight of a phenolic antioxidant (D); and 0.01 to 0.5 parts by weight of a sulfur compound antioxidant (E).
