Abstract

A continuous process for the production of a dynamically vulcanized thermoplastic elastomer comprising a thermoplastic resin and a non-halogenated elastomer with a multiolefin content of greater than 3.5 mol % that has been modified in situ with a carboxylic anhydride. The process provides materials with improved elongation at break and ultimate tensile strength that can be produced economically and with reduced environmental impact.
