Patent ID: 7645832

Claim:
A thermoplastic elastomer having adhesion to steels, said thermoplastic elastomer comprising: a) a hydrosilation dynamically crossliniked rubber, b) from 2.0 to 10 parts of ZnO or a metal salt selected from the group consisting of CaCO 3 and NaHCO 3 , and c) from 10 to 200 parts by weight of a functionalized polyolefin having pendant polar functional groups, wherein said 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 said functionalized polyolefin is derived from polymerizing at least one monoolefin to form the polyolefin or is derived from hydrogenating the polydiene blocks of a block copolymer, and wherein said parts by weight are based on 100 parts by weight of crossliniked rubber.
