Abstract

Thermoplastic elastomer composition comprising 100 parts by weight of a polyester block copolymer and 0.05 to 20 parts by weight of a liquid diphenylmethane diisocyanate, which has a stable high melt viscosity with less variation of viscosity in the production lots and has also excellent flexural fatigue resistance and water resistance and is useful for the production of hollow shaped products such as bellows and section profiles such as moldings by blow molding or extrusion molding.
