Abstract:
A laminar structure comprising(A) a first layer comprising(i) a first polymer comprising an uncured unsaturated polymeric adduct, formed by reacting a polymer having unsaturation in the backbone of the polymer chain with an unsaturated dicarboxylic acid or dicarboxylic acid anhydride, wherein the acid or anhydride moieties comprise at least three weight percent of said adduct;(ii) an elastomer, different from said first polymer;(iii) a compound selected from the group consisting of polyamino primary amines, polyamino primary amine carbamates, and condensation products of polyamino primary amines with aldehydes; wherein the number of equivalents of component (iii) is equal to or greater than the number of equivalents of carboxylic acid moieties or anhydride moieties present in component (i); and(iv) a curing agent for the elastomer of component (ii); and(B) a second layer, in contact with the first layer, comprising a fluoropolymer composition.
