The present invention includes elastomeric compositions of BIMS elastomers
suitable for abrasion resistant, high traction and/or barrier articles.
The compositions and articles made from those compositions of the
inventions 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 C.sub.4 to C.sub.7
isoolefin derived units, p-alkylstyrene derived units and
p-bromomehtylstyrene 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.
