Abstract
A thermoplastic elastomer composition composed of a partially crosslinked product of a blend consisting mainly of (a) 80 to 10 parts by weight of a peroxide-crosslinkable olefinic copolymer rubber, (b) 10 to 80 parts by weight of a peroxide-crosslinkable polyolefin resin having specific properties and (c) 50 to 10 parts by weight of a peroxide-decomposable polyolefin resin, the total amount of (a)+(b)+(c) being 100 parts by weight, the crosslinked product is obtained by dynamically heat-treating said blend in the presence of (d) an organic peroxide. The thermoplastic elastomer has excellent film formability, and is useful as a waterproof sheet.
