IONOMER, METHOD FOR PRODUCING SAME AND MOLDED ARTICLE

摘要

Disclosed is an ionomer which is obtained by reacting metal compound particles having an average particle diameter of not more than 1 µm and a polymer having a structural unit derived from an unsaturated dicarboxylic acid anhydride. Such an ionomer has flexibility and molding workability similar to those of conventional olefin thermoplastic elastomers, while exhibiting good mechanical characteristics, oil resistance and abrasion resistance. In addition, such an ionomer is particularly excellent in tensile break strength and scratch resistance. Also disclosed are a method for producing such an ionomer and an molded article made of such an ionomer.
