Abstract:
A composition for improving adhesion between an elastomer and a fluoropolymer comprising(A) a first polymer comprising an uncured unsaturated polymeric adduct, formed by reacting i) a polymer having unsaturation in the backbone of the polymer chain with ii) an unsaturated dicarboxylic acid or dicarboxylic acid anhydride, wherein the acid or anhydride moieties comprise at least three weight percent of said adduct; (B) a polyhydroxy compound; and (C) a vulcanization accelerator selected from the group consisting of quaternary phosphonium salts and quaternary ammonium salts; wherein the number of equivalents of free hydroxyl moieties present in the polyhydroxy compound of (B) is equal to or greater than the number of equivalents of carboxylic acid moieties or anhydride moieties present in the first polymer of (A).
