Abstract

Abstract A neutralized sulfonated EPDM terpolymer is rendered amenable to adhesion utilizing typical foot sole primer/adhesive systems by incorporating into the sulfonated EPDM a syndiotactic 1,2-polybutadiene. The composition preferably includes process oils; inorganic fillers and preferential plasticizers for the neutralized sulfonated EPDM terpolymer.
