The present invention includes elastomeric compositions of BIMS elastomers suitable for abrasion resistant, high traction and/or air barrier articles. The compositions and articles made from those compositions of the invention can be described in any number of embodiments. In one embodiment, the composition suitable for an abrasion resistant article includes from 5 to 100 phr of a terpolymer of C4 to C7 isoolefin derived units, p-alkylstyrene derived units and p-bromomethylstyrene derived units; at least one filler such as carbon black, silica, precipitated silica, clay, or combinations thereof, and from 0.1 to 3 phr of at least one thiourea. The composition can also include from 5 to 80 phr of at least one elastomer selected from natural rubbers, polyisoprene rubber, styrene butadiene rubber (SBR), polybutadiene rubber, isoprene butadiene rubber (IBR), styrene-isoprene-butadiene rubber (SIBR), butyl rubber, halogenated butyl rubber, butadiene-acrylonitrile-styrene rubber (SNBR), and mixtures thereof. The composition can be cured by using one or a combination of curatives known in the rubber industry. For example, the composition may include from 0.1 to 10 phr of at least one of a peroxide, sulfur, a metal oxide, or a combination thereof. In a further embodiment, the thiourea is present from 0.2 to 1.5 phr in the composition.
