<p>An olefinic thermoplastic elastomer having improved properties can be prepared by kneading a graft copolymer, an acrylic rubber, a crosslinking agent and a crosslinking coagent together under melting. The graft copolymer is composed of an olefin polymer segment prepared from an α-olefin monomer and a vinyl polymer segment prepared from a vinyl monomer, one of the segments being dispersed in the other segment in the form of particles whose diameters range from 0.01 to 1μm. The acrylic rubber can be obtained by polymerizing a monomer mixture containing methoxyethyl acrylate.</p> |
