加工ならびに機能性の付与ができなかった。Ester or urethane thermoplastic elastomers have poor heat resistance and poor versatility. Also, the material cost is high and the hardness variation is small. In contrast, styrene-based or olefin-based thermoplastic elastomers have good weather resistance, many variations in hardness, and excellent elastic properties, but they have no reactive groups, so they have poor adhesion to inks and paints. It was very poor, and it was not possible to perform secondary processing such as surface treatment and decoration of the molded product and to impart functionality.
