Abstract

PURPOSE: The titled composition useful as a raw material for molding, having high rate of crystallization, crystallizing quickly, obtained by blending a thermoplastic polyester with an organic polymer having an esterified carboxyl group.
CONSTITUTION: 100pts.wt. Thermoplastic polyester having an intrinsic viscosity 0.5W2.0, preferably polyethylene terephthalate, etc., is blended in molten state with 0.1W10pts.wt. compound, as a crystallization promotor, obtained by esterifying partly or completely the carboxyl group or acid anhydride group of an organic polymer (e.g., ethylene-acrylic acid copolymer, etc.) having a carboxyl group or acid anhydride group with a polyalkylene glycol, preferably a polyaklylene glycol having an average molecular weight 100W8,000 so that an equivalent - 1/10 equivalent carboxyl or acid anhydride group is esterified.
