    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.
