ABSTRACT:
This invention relates to plasticized metal neutralized sulfonated EPDM terpolymers having at least 65 wt. % of ethylene in the backbone of the EPDM terpolymer and extended compositions of these metal neutralized sulfonated EPDM terpolymers having 100 parts of a neutralized sulfonated EPDM terpolymer; less than about 100 parts per hundred of a non-polar process oil; less than about 300 parts per hundred of a filler; and a preferential plasticizer at about less than 60 parts per hundred based on 100 parts of the sulfonated elastomeric polymer. These compositions can be readily processed due to their superior rheological properties on conventional plastic fabrication equipment, especially on low pressure injection molding and extrusion equipment into elastomeric articles having improved physical properties.
