Abstract
This invention relates to an improved elastomeric composition of metal and ammonium neutralized sulfonated elastomeric polymers which are preferentially plasticized with a critically selected non volatile amine at a minimum critical concentration level of at least 8 parts by weight based on 100 parts by weight of the metal neutralized elastomeric polymer, wherein the plasticized compositions have improved physical or rheological properties. These elastomeric compounds can be processed on conventional plastic fabrication equipment.
