Abstract
This invention relates to improved elastomeric compositions of metal and ammonium neutralized sulfonated EPDM terpolymers which are preferentially plasticized with an aliphatic organic amide at a minimum critical concentration level of at least 8 parts by weight based on 100 parts by weight of the metal neutralized EPDM terpolymer, wherein the composition has a balance of improved physical and rheological properties. These compositions can be readily processed due to their superior rheological properties on conventional plastic fabrication equipment.
