Abstract: An elastomer composition can comprise a C4 to C7 isoolefin; a non-halogenated alkylstyrene; a halogenated alkylstyrene; and optionally a diolefin, wherein the C4 to C7 isoolefin is not the same as the diolefin. Optionally, the elastomer composition can be blended with a butyl rubber and/or a halobutyl rubber. Such blends that also comprise additives may be suitable for producing tire components such as innerliners.

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.

Abstract: This invention relates to a brominated elastomer composition comprising a free radical scavenger. The scavenger is present in the amount of at least about 0.05 wt % of the composition. The scavenger is added to the composition so that the Mooney viscosity of the composition does not increase by more than about 15% to about 40%, for up to about 15 days at 80° C. The scavenger can be a sterically hindered nitroxyl ether, a nitroxyl radical, or both.
