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: 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.
