Claim Text:
1. A thermoplastic vulcanizate composition consisting of: from 5 wt % to 95 wt %, based on the total weight of the thermoplastic vulcanizate composition, of a propylene/α-olefin copolymer comprising from 1 to 20 percent by weight of units derived from α-olefin and characterized by a g′ ratio of less than 1, measured at interpolymer number average molecular weight (Mn), an MFR (2.16 kg @ 230° C.) greater than or equal to 0.01, a density greater than or equal to 0.850 g/cc, and a molecular weight distribution, Mw/Mn, less than or equal to 3.5; from 5 wt % to 95 wt %, based on the total weight of the thermoplastic vulcanizate composition, of an ethylene-propylene-diene-rubber having a density from 0.85 to 0.88 g/cc, I optionally, one or more additives selected from the group consisting of, colored pigments, stabilizers, antidegradants, flame retardants, processing aids, adhesives, tackifiers, plasticizers, waxes, and discontinuous fibers wherein the thermoplastic vulcanizate composition has a tensile strength at break of greater than or equal to 8 MPa and tear strength at 23° C. of at least 190 lb-f/in.
