ABSTRACT:
The present invention relates to a polyester block copolymer composition which is obtained by reacting 0.5 to 5.0 parts by weight of an epoxy compound (C) having two or more functionalities with 100 parts by weight of a polyester block copolymer (P) having an acid value of 0 to 5 mgKOH/g obtained by reacting a crystalline aromatic polyester (A) having a hydroxyl group at a molecular terminal with a lactone (B) and optionally with a polyfunctional compound (D) having three or more groups selected among carboxyl, hydroxyl, and/or ester groups thereof. The composition has such excellent moldability that it is applicable to molding techniques including blow molding without arousing any trouble. It is satisfactory in heat resistance, water resistance, impact resistance, or flame retardancy, and has rubber-like elasticity.
