Thermoplastic elastomer composition having viscosity-enhanced and vulcanized elastomer dispersions

摘要

A thermoplastic elastomer composition having improved mechanical properties and fatigue resistance comprising (A) a halogenated isobutylene elastomer, (B) polyamide and (C) an amine component selected from tertiary amines and secondary diamines, wherein the elastomers are dispersed as a domain in a continuous phase of the polyamide.
