The dynamic vulcanisation alloy comprises at least one isobutylene-containing elastomer, at least one thermoplastic resin, and an anhydride functionalized oligomer grafted to the thermoplastic resin. In the alloy, the elastomer is present as a dispersed phase of the sulphided or partially vulcanized particles in the continuous phase of the thermoplastic resin, and the alloy is substantially free of sulphonamide. |
