High temperature stable, low solvent swelling thermoplastic elastomer compositions

摘要

Thermoplastic elastomer compositions comprise a blend of polyamide resin and a covalently-crosslinked acrylate rubber. Such compositions can be prepared by dynamic vulcanization of the rubber in admixture with the polyamide and can exhibit high temperature dimensional stability and low oil swell. The compositions can be used to form a variety of molded, extruded, or calendered articles.
