    • 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.
    • 具有改善的表面具有极性官能团的基材的粘附性的丁基橡胶离聚物。 这种基材的实例包括不锈钢,玻璃,聚酯薄膜或聚四氟乙烯。 丁基橡胶离子交联聚合物对基材的粘附性比非离聚物丁基橡胶对相同基材表面的粘附性大至少25%,并且某些基材的粘合力大于150%以上。 随着丁基橡胶离子交联聚合物中多烯烃含量的增加,粘附性得到改善。 对于具有高多烯烃含量(至少3.5摩尔%的多烯烃单体或至少1.5摩尔%的残余多烯烃)​​的丁基橡胶离聚物,粘合力最大。 通过利用这些高粘附性水平,可以在丁基橡胶离聚物和基材之间形成复合制品。
