Zusammenfassung:Disclosed are blends of a propylene-based polymer, an elastomer, and optionally an ethylene-based polymer, having improved low temperature toughness, and methods of making such blends. The elastomer is preferably a copolymer of ethylene, one or more C3-C20 alpha -olefin comonomers, and optionally one or more non-conjugated diene comonomers, having an MLRA/ML ratio of at least 8 and an ethylene content of from 74 to 95 mole percent.
