Abstract
An olefinic thermoplastic elastomer with improved properties can be obtained by melting and kneading a graft copolymer, acrylic rubber, a crosslinking agent, and a co-crosslinking agent. The graft copolymer is composed of an olefin polymer segment formed from a nonpolar α-olefin monomer and a vinyl polymer segment formed from a vinyl monomer, with particles of one segment being dispersed in the other segment. The particle diameter is 0.01 to 1 μm. The acrylic rubber can be obtained by polymerizing a monomer mixture containing methoxyethyl acrylate.
