Zusammenfassung:	PURPOSE:To obtain a molded article excellent in impact resistance and heat resistance, by molding a mixture of a composition comprising a thermoplastic polyester and an impact resistance improver with a composition comprising said polyester and a crystallization accelerator. CONSTITUTION:A composition (A) is obtained by melt-kneading 100pts.wt. thermoplastic polyester (a) (e.g., polyethylene terephthalate) with 2-100pts.wt. impact resistance improver (b) which is a lowly crystalline or amorphous copolymer, preferably, of a crystallinity (X-ray diffractometry)
