Zusammenfassung:Thermoplastic vulcanizate compositions and articles exhibiting superior elastomeric performance and adhesive properties, and methods of making same are characterized by comprising a thermoplastic phase and a rubber phase. The thermoplastic phase comprises a thermoplastic polyolefin, and the rubber phase comprises an amorphous propylene-ethylene copolymer having: a Mn of from 20 kg/mol to 3,000 kg/mol, a Mw/Mn of 10.0 or lower, an ethylene percentage by weight of from about 2 wt. % to about 50 wt. %, a diene percentage by weight of from about 0 wt. % to about 21 wt. % and a heat of fusion of less than 5 J/g.
