Claim:
1. A thermoplastic vulcanizate composition comprising: a polymeric composition consisting of a continuous phase, a discontinuous phase, and a compatibilizer; the continuous phase consisting of a first propylene-based polymer consisting of propylene and ethylene; the discontinuous phase dispersed in the continuous phase, the discontinuous phase consisting of a crosslinked ethylene/α-olefin multi-block copolymer consisting of ethylene and octene; the compatibilzer consisting of a second propylene-based polymer different than the first propylene-based polymer and consisting of propylene and ethylene; the polymeric composition consisting of from 5 wt % to 50 wt % of the first propylene-based polymer; from 15 wt % to 76 wt % of the crosslinked multi-block copolymer; and from 1 wt % to 40 wt % of the second propylene-based polymer that has a density that is different than the density of the first propylene-based polymer; and the thermoplastic vulcanizate composition is void of an ethylene-propylene-diene monomer rubber.
