    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: Preparation of butyl rubber based graft co-polymers from halobutyl elastomers using phase transfer catalysts in the presence of a solution of an alkali metal salt of an oxygen or sulfur nucleophile that is bound to a polymeric substrate. Graft co-polymers can be produced of a butyl polymer (isobutene-coisoprene) and polymeric substrates such as polyethylene, polypropylene, polystyrene, polybutadiene, polysilanes, polysiloxanes, polyethylene glycol, polyethylene oxide, polyphosphazenes, polyferrocenes or their hybrids.
