    Abstract: Curative systems for butyl based compositions are provided herein. The present curative systems provide consistent curing speeds for butyl based compositions, low moduli at low strain, higher elongation and higher percent retention in elongation at heat aging conditions. The curative systems have about 0.5 phr to about 3 phr metal oxide, about 0.3 phr to about 3 phr fatty acid, at least to about 2 phr sulfur, and at least about 2 phr of cure accelerator.

    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.
