A method for producing an olefinic thermoplastic elastomer comprising the steps of kneading an olefin copolymer rubber (A) obtained by polymerizing ethylene, an α-olefin having 3 to 20 carbon atoms and a non-conjugated polyene, a volatile organic solvent (B) and, an olefin resin (C) in an extruder, removing the volatile organic solvent (B) while kneading, then adding a crosslinking agent (E) and further removing the volatile organic solvent (B) while kneading in the extruder to obtain the olefinic thermoplastic elastomer. |
