TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The highly weatherable layer comprises functionalized or non-functionalized polyvinylidene fluoride, ethylene tetrafluoroethylene, terpolymer of ethylene with tetrafluoroethylene and hexafluoropropylene, terpolymer of tetrafluoroethylene-hexafluoropropylene-vinyl fluoride, vinyl fluoride copolymer which can be melt processed, and blend of polyvinylidene fluoride with poly(methyl methacrylate) polymer and copolymer. The highly weatherable layer and high-deformation temperature layer exist as a single layer with thickness of 25 mu m or more. The polyvinylidene fluoride layer comprises blend of 60 weight% or more of polyvinylidene fluoride with poly(methyl methacrylate). The tie layer comprises polyvinylidene fluoride blended with compatible polymer, functionalized polyvinylidene fluoride, functional polyolefin, and blend of functional olefin with non-functional olefin, blends of polyvinylidene fluoride with anhydride containing poly(methyl methacrylate), blends of polyvinylidene fluoride with acid-containing poly(methyl methacrylate), and/or polyester thermoplastic polyurethane. The polyolefin comprises non-functional polyolefin chosen from ethylene, propylene, 1-butene, 1-hexene, 1-octene or 1-decene and olefin copolymers with one or more alkyl(meth) acrylates, or functional polyolefin chosen from terpolymer of ethylene-butyl acrylate-maleic anhydride, ethylene-methyl acrylate-maleic anhydride, ethylene-ethyl acrylate-maleic anhydride, ethylene-methyl acrylate-glycidyl methacrylate, grafted polyolefin, ethylene vinyl acetate, polyamide-grafted polyolefin and amine-terminated polyamide. The film structure contains polyvinylidene fluoride- anhydride functional poly(methyl methacrylate)-polyamide, polyvinylidene fluoride-anhydride functional poly(methyl methacrylate) blend-polyamide-functional polyolefin, polyvinylidene fluoride-polyvinylidene fluoride-acid functional poly(methyl methacrylate) blend-functional polyolefin and/or polyvinylidene fluoride-polyvinylidene fluoride- acid functional poly(methyl methacrylate) blend-functional polyolefin-polyolefin. One or more layers in the multilayer film structure further comprises additives chosen from impact modifier, ultraviolet stabilizer, plasticizer, filler, coloring agent, titanium dioxide, zinc oxide, antioxidant, antistatic agent, surfactant, toner, pigment, matting agent, adhesion promoter and dispersant. The polyolefin layer further comprises woven or non-woven mesh or scrim. The multilayer film in the multilayer film structure further has layer of encapsulant material on the side of the film directly adjoining the polyamide or polyolefin layer. Preferred Properties: The multilayer film in the multilayer film structure has total film thickness of 25 to less than 250 mu m, and absorbance of more than 1, at 360 nm. The polyolefin layer has thickness of 200-750 mu m. The thickness of the highly weatherable layer and high-deformation temperature layer is 1-125 mu m, and 50-125 mu m, respectively.
