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.
