    摘要: A butyl rubber ionomer having improved adhesion to substrates whose surfaces have polar functional groups. Examples of such substrate materials include stainless steel, glass, mylar or Teflon®. The adhesion of the butyl rubber ionomer to the substrate is at least 25% greater than the adhesion of a non-ionomeric butyl rubber to the same substrate surface and with certain substrates is more than 150% greater. The adhesion is improved with increasing levels of multiolefin content in the butyl rubber ionomer. The adhesion is greatest for butyl rubber ionomers having a high multiolefin content (at least 3.5 mol% of multiolefin monomers or at least 1.5 mol % of residual multiolefins). By taking advantage of these high adhesion levels, a composite article can be formed between the butyl rubber ionomer and the substrate.

    摘要: A peroxide cured rubber composition comprising a first peroxide curable rubber compound comprising a hydrogenated nitrile-butadiene rubber compound (HNBR); a second peroxide curable rubber compound comprising repeating units derived from at least one isoolefin monomer, more than 3.0 mol% of repeating units derived from at least one multiolefin monomer, and a gel content of less than 5.0 wt%; and, repeating units derived from at least one multiolefin cross-linking agent. In a preferred embodiment, the second peroxide curable rubber comprises a peroxide curable butyl rubber (IIR) with a high isoprene content and a low gel content. The composition is particularly useful in the making of hydrocarbon resistant seals. A method of producing the composition is also disclosed, along with a shaped article made from the composition.
