<p>A butyl rubber ionomer is provided to ensure more improved surface adhesion to the surface of a substrate than that of non-ionomer butyl rubber. A butyl rubber ionomer comprises (a) a repeat unit derived from at least one isoolefin monomer, at least 0.5mol% of a repeat unit derived from at least one multiolefin monomer, at least 0.5mol% of a repeat unit derived from allyl halide, and at least 0.5mol% of an ionomer moiety, and has (b) an adhesion to a substrate surface 25% higher than an adhesion of non-ionomer butyl rubber to the same substrate surface. The isoolefin includes isobutylene. The multiolefin includes isoprene. The allyl halide includes bromide.</p> |
