Thermoplastic elastomer composition and process for production thereof and low permeability hose using the same

Abstract

A thermoplastic elastomer composition comprising: i) from 15 to 80 parts by weight of a polyamide thermoplastic resin as component A; ii) from 20 to 85 parts by weight of a rubber composition as component B, the rubber composition containing a copolymer rubber composed of a copolymer of a C.sub.4 to C.sub.7 isomonoolefin and a p-alkylstyrene, where at least a part of the p-alkylstyrene unit portions thereof have a halogen atom; and iii) a cross-linking agent, wherein the thermoplastic resin component A forms a continuous phase and at least part of component B is dispersed in component A as a dispersed phase and at least part of the dispersed phase is cross-linked by the cross-linking agent.
