THERMOPLASTIC ELASTOMER COMPOSITIONS COMPRISING A PARTIALLY CROSSLINKED BLEND OF A PEROXIDE CROSSLINKING OLEFIN COPOLYMER RUBBER, OPTIONALLY AN OLEFINIC PLASTIC AND AN UNSATURATED CARBOXYLIC ACID OR DERIVATIVE

摘要

A partially crosslinked thermoplastic elastomer composition having an excellent heat-bondability is obtained by dynamically heat-treating a peroxide-crosslinking olefin copolymer rubber with an alpha , beta -unsaturated carboxylic acid or a derivative thereof in the presence of an organic peroxide.
