    Abstract: A thermoplastic polyester resin composition is obtained by blending, per 100 parts by weight of (A) a thermoplastic polyester resin, 0.1 to 5 parts by weight of (B) a novolac type epoxy resin having a specific structure, and 0.05 to 10 parts by weight of (C) an epoxy compound having two epoxy functional groups per molecule. Thus, a molded article that exhibits superior melt stability with respect to a wide range of processing temperatures, has excellent mechanical properties and heat resistance, and exhibits superior long-term hydrolysis resistance, chemical resistance, and oxidative deterioration resistance can be obtained.

    Abstract: A thermoplastic polyester resin composition includes 0.05 to 10 parts by weight of an epoxy compound (B) and 0.001 to 1 part by weight of a hindered amine compound (C) with respect to 100 parts by weight of a thermoplastic polyester resin (A) having an amount of carboxyl groups of 50 eq/t or less. The thermoplastic polyester resin composition is capable of producing a molded article which is excellent in mechanical properties and heat resistance, as well as in long-term hydrolysis resistance, and has a small decrease in mechanical properties and hydrolysis resistance even when melt-processed at a high temperature of 270° C. or more.
