Abstract
Abstract This invention relates to an improved elastomeric composition of metal neutralized sulfonated elastomeric polymers which are plasticized with critically selected polydentate amines wherein the plasticized compositions have improved rheological properties. These elastomeric compositions can be processed on conventional plastic fabrication equipment into high performance elastomeric articles.
