PURPOSE:To improve heat resistance, impact resistance, appearance, etc., by compounding a specified thermoplastic polyester, a crystallization accelerator, an alpha-olefin-glycidyl unsatd. carboxylate copolymer, a glass fiber and a coloring agent contg. TiO2. CONSTITUTION:100 pts.wt. (hereinbelow described merely as pts.) thermoplastic polyester (A) consisting of polyethylene terephthalate of an intrinsic viscosity of 0.35-1.20, an ethylene phthalate oligomer of an intrinsic viscosity of 0.35-1.20 and a polyether compd. and having a content of a unit derived from the polyether compd. of 2-30wt.%, 0.05-20 pts. crystallization accelerator (B) (e.g. sodium palmitate), 0.5-50 pts. copolymer (C) consisting of 70-99wt.% alpha-olefin and 30-1wt.% glycidyl alpha,beta-unsatd. carboxylate (e.g. ethylene-glycidyl acrylate), 10-150 pts. glass fiber (D) with a fiber length of 1.5-50mm and 0.1-90 pts. coloring agent (E) contg. 80wt.% or more TiO2. |
