    摘要: An adhesive polymer comprising a maleic anhydride grafted butyl rubber and a polymer compound made from the adhesive polymer further comprising a functionalized siliceous nanoclay. The adhesive polymer and polymer compound exhibit greatly improved adhesion to certain substrate surfaces. Examples of substrate materials include stainless steel, glass, mylar or Teflon®. The greatest adhesion was observed in polymer compounds comprising maleic anhydride grafted butyl rubber produced according to a solution process and from 5 to 15 phr of a montmorillonite nanoclay. The adhesion is improved with increasing levels of nanoclay content in the compound up to a limit where filler-filler interactions occur.

    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.
