PURPOSE:To provide a polyester resin composition having high crystallization rate and excellent moldability in a low-temperature mold, giving a molded article having excellent mechanical properties, electrical properties and weather resistance and suitable for electrical and electronic parts, automobile parts, etc. CONSTITUTION:The objective composition is produced by compounding (A) 100 pts.wt. of a polyester resin produced by adding 0.01-20 pts.wt. of an organic sulfonic acid salt containing phenolic hydroxyl group and expressed by formula (Ar is 6-30C aromatic ring; M is alkali metal or alkaline-earth metal; m is 1 or 2; n is 1-5) to 100 pts.wt. of a thermoplastic polyester composed of a 8-20C aromatic dicarboxylic acid or its lower alkyl ester and a 2-20C diol before the completion of the polycondensation reaction of the polyester, (B),5-140 pts.wt. of a reinforcing or filling material and (C) 0.1-10 pts.wt. of a polyether ester amide consisting of (C1) an aminocarboxylic acid, a lactam or a salt of a diamine and a dicarboxylic acid, (C2) a poly(alkylene oxide) glycol having a number-average molecular weight of 200-600 and (C3) a dicarboxylic acid. |
