Abstract
A thermoplastic elastomer having adhesion to steels, where the thermoplastic elastomer includes a dynamically crosslinked rubber, from more than 2.0 to 10 parts of a metal oxide or salt, and from 10 to 200 parts by weight of a functionalized polyolefin having pendant polar functional groups, where the polar functional groups are present at a level of 0.5 to 3.5 mole percent of the total repeating units of said functionalized polyolefin and the functionalized polyolefin is derived from polymerizing at least one monoolefin to form a semicrystalline polymer or is derived from hydrogenating the polydiene blocks of a block copolymer, and where the parts by weight are based on 100 parts by weight of crosslinked rubber.
