Abstract
PURPOSE: The titled composition for forming a molded article with good surface, having high crystallization temperature, crystallizing abruptly, obtained by blending a thermoplastic polyester with a metal-containing olefin-unsaturated carboxylic acid copolymer and a polyalkylene glycol.
CONSTITUTION: 100pts.wt. Thermoplastic polyester having an intrinsic viscosity usually 0.5W2.0 is blended in molten state with 0.1W30pts.wt. copolymer of an α- olefin and an α,β-unsaturated carboxylic acid, preferably copolymer having not less than 50mol% α-olefin and partly or completely neutralized carboxyl groups, especially a metal-containing polymer having not less than 10mol% carboxyl groups neutralized by sodium or potassium, as a crystallization accelerator, and 1W 20pts.wt. polyalkylene glycol shown by the formula I (P is 2W10; n is a number to make the number average molecular weight of a polyether having a repeating unit shown by the formula II 1,000W10,000.
