(57) [abstract] (with correction) [PROBLEMS] Moldability, appearance (glossiness), slidability (slidability), containing an olefin resin and an ethylene-α-olefin copolymer rubber as a polymer component. A crosslinked thermoplastic elastomer composition for injection molding having excellent wear resistance and flexibility. SOLUTION: (A) 5 to 50 parts by weight of an olefin resin (B) Ethylene-α-olefin copolymer rubbers 5 to 5 (D) 0.1 to 5 parts by weight of fatty acid amide per total amount of (C) 1 to 80 parts by weight of mineral oil is subjected to dynamic heat treatment in the presence of a crosslinking agent to obtain the following formula: A satisfactory composition. MFR> 0.113e 0.093Hs (MFR: JIS K7250 (230 ° C., 98.07 Melt flow rate measured according to N), Hs: A Shore A hardness measured according to STM D2240, e: base of natural logarithm) |
