TECHNOLOGY FOCUS - POLYMERS - Preferred Method: At least a portion of the carboxylate groups or the carboxylic acid groups of copolymer (I) are reacted with at least a portion of the epoxy groups of copolymer (II) to form cross-links between the copolymer (I) and copolymer (II). An additional layer is adhered to the surface of the encapsulant layer opposite the surface that contacts portions of the surface of the second layer. The surface of the first film layer that is in contact with the second film layer is modified with an aminosilane. Preferred Components: The first olefin is n-butyl acrylate and the second olefin is acrylic acid or methacrylic acid. The third olefin is glycidyl methacrylate. The surface of the first film layer is modified with an aminosilane. The encapsulant layer comprises a polymeric material selected from ethylene acid copolymers, ionomers of ethylene acid copolymers, ethylene vinyl acetate copolymers, poly(vinyl acetals), polyurethanes, polyvinylchlorides, polyethylenes, polyolefin block copolymer elastomers, copolymers of alpha -olefins and alpha , beta -ethylenically unsaturated carboxylic acid esters, silicone elastomers, and/or epoxy resins. The blend composition is at least partially crosslinked. Preferred Definitions:    R1, R3, R4=H or a methyl;    R2=butyl group;    D'=R5;    R5=a moiety containing a glycidyl group.    EXAMPLE - Sodium ionomer (comprising ethylene/methacrylic acid dipolymer, methacrylic acid (MAA) (11 wt.%), neutralized, Na+ cation (37%)); and EBAGMA-1 (RTM: terpolymer containing copolymerized units (28 wt.%) of n-butyl acrylate and copolymerized units (5.25 wt.%) of glycidyl methacrylate, the remainder copolymerized units of ethylene), in a weight ratio of 60:40 were blended at 20 degrees C for 5 minutes. Plaques having thickness of 30 mil were formed by compression molding portions of each blend at 120 degrees C for 5 minutes. The compression-molded plaques without silane were laminated to test fluoropolymer sheets using a vacuum bag lamination method. The adhesion between the second layer and the fluoropolymer film was tested by a 180 degrees peel test, initially after lamination and after damp heat treatment. After exposure to damp heat conditions for 264 hours, the film exhibited improvements in adhesion to each of the three fluoropolymer films.
