<p>A composition comprising a dynamically-vulcanized rubber, and a copolymer of propylene and at least one of (i) an ±, internal non-conjugated diene monomer and (ii) an olefin containing a labile hydrogen, where the copolymer includes from about 0.1 to about 10 mole percent by weight units deriving from ±, internal non-conjugated diene monomer or from about 0.5 to about 10 mole percent units deriving from an olefin containing a labile hydrogen, and where the compositional distribution of the ±, internal non-conjugated diene monomer or the olefin containing a labile hydrogen is narrow as determined by a crystallization temperature distribution parameter R that is less than 2.0.</p> |
