Abstract: A thermoplastic vulcanizate comprising (i) a dynamically-cured rubber, and (ii) a thermoplastic polymer component, where the thermoplastic polymer component includes (a) a propylene-?-olefin thermoplastic copolymer characterized by including at least 5% by weight up to 35% by weight units deriving from ?-olefins, and having a heat of fusion, as determined by DSC, of less than 80 J/g, (b) and a functionalized thermoplastic polymer.

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.
