PURPOSE:The titled resin composition producing, with good moldability, a molded article having excellent mechanical strength and dimensional stability, made by compounding a polyethylene terephthalate resin, glass fibers, a nucleating agent, and a specified benzoic ester. CONSTITUTION:30-90wt% polyethylene terephthalate resin (with the intrinsic viscosity of about 0.4-1.4), 5-60wt% glass fibers (chopped strands of a length of about 0.4-6mm.), 0.03-30wt% nucleating agent (e.g. sodium stearate), and 0.1- 10wt% benzoic ester of formula I, II or III (where n and m are each 1 or greater) (e.g. a compound of formula IV), are compounded (the total composition being 100wt%). |
