Thermoplastic elastomer composition of an elastomer and a non-elastomeric polyolefin which is functionalized with an anhydride of an organic carboxylic acid

Abstract

A thermoplastic elastomer composition is disclosed that includes an elastomer and a non-elastomeric polyolefin, which is functionalized with an anhydride of an organic carboxylic acid. Furthermore, the use of a mixture of an elastomer and a cross-linking agent for the elastomer for producing a thermoplastic elastomer composition are disclose. A further subject of the invention is the use of a non-elastomeric polyolefin which is functionalized with an anhydride of an organic carboxylic acid for producing a thermoplastic elastomer composition according to the invention. In addition, the invention relates to the use of a thermoplastic elastomer composition according to the invention for producing an article/composite material with a polyamide. The invention also relates to a process for producing a thermoplastic elastomer composition according to the invention as well as a composite material made of the thermoplastic elastomer composition according to the invention with a polyamide.
