Abstract
This invention relates to an improved elastomeric composition of metal neutralized sulfonated polymers which are plasticized with a preferential plasticizer at a concentration level of at least 1 part by weight based on 100 parts by weight of the metal neutralized EPDM terpolymer, wherein the preferential plasticizer is a metal rosin salt. The resultant compositions have improved physical properties and can be processed on conventional plastic fabrication equipment.
