Abstract:
1. A thermoplastic elastomer composition comprising (A) at least one halogenated isobutylene-containing elastomer; and (B) at least one nylon resin having a melting point of about 170° C. to about 260° C.; and (C) a plasticizer comprising polyamide having a weight average molecular weight of 20,000 Daltons or less; wherein: (1) said at least one elastomer is present as a dispersed phase of small vulcanized particles in a continuous phase of said nylon; and (2) said elastomer particles have been formed by dynamic vulcanization; and wherein (3) said plasticizer (C) has a viscosity at 200° C. of less than about 15 Pa·s.
