PROBLEM TO BE SOLVED: To provide an urethane composition excellent in scratch resistance of the surface of molded products therefrom, and excellent in flexibility, heat resistance, low-temperature characteristics, weatherability, mechanical strength and molding processability, therefore useful in automobiles, home appliances, toys, miscellaneous goods, etc., and because of being high in scratch resistance of the surface of the molded products therefrom, enabling the coating process for the molded products to be obviated and thereby, their high productivity and low cost to be realized. SOLUTION: This urethane composition as a thermoplastic elastomer composition comprises (A) 100 pts.wt. of a polyurethane elastomer, (B) 3-100 pts.wt. of a carboxylic acid-modified polymer where carboxylic acid group or its derivative group is bound in the molecule, and (C) 10-900 pts.wt. of a rubbery elastomer. |
