    Abstract: A heterogeneous vulcanized polymer blend comprising a continuous phase comprising a thermoplastic polypropylene having a crystallinity of at least 30% and a dispersed phase comprising particles of an elastomeric copolymer dispersed in the continuous phase and having an average particle size of less than 5 micron. The elastomeric copolymer has a crystallinity of less than 20% and is at least partially cross-linked such that no more than about 80 wt % of the elastomeric copolymer is extractable in cyclohexane at 23° C.
