Abstract:
1. A dynamically vulcanized alloy comprising the four following components: a) at least one isobutylene-containing elastomer; b) at least one polar thermoplastic resin, c) an anhydride functionalized oligomer, wherein the oligomer, prior to functionalization, has a molecular weight in the range of 750 to 1250, and d) a plasticizer, the plasticizer comprising a component selected from the group consisting of tertiary amines, secondary diamines, and sulfonamides, wherein the anhydride functionalized oligomer and the plasticizer are present in the alloy in a ratio ranging from 0.3 to 1.5, and wherein the anhydride functionality of the oligomer is grafted to the polar thermoplastic resin and the elastomer is present as a dispersed phase of small vulcanized or partially vulcanized particles in a continuous phase of the thermoplastic resin.
