Abstract
A thermoplastic vulcanizate composition comprised of (a) thermoplastic resin selected from the group consisting of polyphenylene ether, polypropylene, polyethylene, and polystyrene, (b) at least one elastomer selected from the group consisting of butadiene-isoprene copolymer rubbers, copolymers of a conjugated diolefin monomer and an acrylate monomer, copolymers of a conjugated diolefin monomer and an methacrylate monomer, copolymers of a conjugated diolefin monomer and a vinyl aromatic monomer, copolymers of a conjugated diolefin monomer and an acrylonitrile monomer, blends of polyisoprene rubber with styrene-butadiene rubber, wherein the elastomer is at least partially crosslinked, wherein the repeat units in the elastomer are distributed throughout the elastomer in an essentially random manner, and (c) oil.
