PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer that is excellent in sealability as well as strength.SOLUTION: A thermoplastic elastomer is obtained by dynamically crosslinking a mixture comprising (A) acrylic rubber 100 pts. mass and (B) thermoplastic polyolefin 15-70 pts. mass, on the condition that (C) crosslinking agent 0.1-5 pts. mass is used relative to (A) acrylic rubber 100 pts. mass. (A) acrylic rubber comprises (a-1) at least one selected from acrylic acid alkyl ester monomer or acrylic acid alkoxyalkyl ester monomer of 70-100 pts. mass, (a-2) unsaturated nitrile monomer of 0-30 pts. mass, and (a-3) vinyl acetate monomer of 0.5-5 pts. mass, but comprises no polyfunctional monomer.SELECTED DRAWING: None |
