<P>PROBLEM TO BE SOLVED: To provide a crosslinked thermoplastic elastomer composition having more excellent oil resistance than conventional crosslinked thermoplastic elastomers and having mechanical properties comparable to those of conventional crosslinked thermoplastic elastomers, a method for producing the composition, and a molded body comprising the composition. <P>SOLUTION: The crosslinked thermoplastic elastomer composition (D) is obtained by reacting a polyester polycarboxylic acid (G) with a multi-valent isocyanate in the presence of a crystalline olefin polymer (A), wherein the multi-valent isocyanate is preferably a diisocyanate and a tri- or higher-valent polyisocyanate, or the multi-valent isocyanate is preferably a diisocyanate and the reaction is preferably conducted with an NCO index obtained from the diisocyanate and the polyester polycarboxylic acid (G) within the range of 1.4-2.9. <P>COPYRIGHT: (C)2011,JPO&INPIT |
