Patent ID: 6846877

Claim:
A thermoplastic elastomer composition comprising a blend of: (a) from about 40 to about 58 weight percent of a thermoplastic vulcanizate comprising a thermoplastic olefin homopolymer or copolymer and olefin rubber; (b) from about 10 to about 35 weight percent of a block copolymer comprising rigid blocks of vinyl aromatic monomers and non-rigid blocks of dienes and vinyl aromatic monomers containing at least the block structure S-B/S-S, wherein the diene content is less than about 40 weight percent of the total block copolymer and the non-rigid blocks B/S amount to at least about 50 weight percent of the total block copolymer; and (c) from about 2.5 to about 45 weight percent of a monovinylidene aromatic monomer modified with an elastomeric polymer.
