Title (EN) FLUOROPOLYMERIC MULTILAYER OPTICAL FILM AND METHODS OF MAKING AND USING THE SAME
(FR) FILM OPTIQUE MULTICOUCHE FLUOROPOLYMÈRE ET SES PROCÉDÉS DE FABRICATION ET D'UTILISATION
Abstract:
(EN) An article, method of using, and method of making a multilayer optical film comprising an optical stack, wherein the optical stack comprises a plurality of first optical layers, each first optical layer comprising a melt-processible copolymer comprising interpolymerized monomers of tetrafluoroethylene, with the proviso that the melt-processible copolymer is not fluorinated ethylene-propylene copolymer or a perfluoroalkoxy resin; and a second polymer layer disposed in a repeating sequence with the plurality of first optical layers, each second optical layer comprising a non-fluorinated polymeric material selected from the group consisting of poly(methyl methacrylate); copolymers of poly(methyl methacrylate); polypropylene; copolymers of polypropylene; polystyrenes; copolymers of styrene; polyvinylidene chloride; polycarbonates; thermoplastic polyurethanes; copolymers of ethylene; cyclic olefin copolymers; and combinations thereof is described.
(FR) L'invention concerne un article, un procédé d'utilisation et un procédé de fabrication d'un film optique multicouche qui comprend un empilement optique, l'empilement optique comprenant une pluralité de premières couches optiques, chaque première couche optique comprenant un copolymère usinable à l'état fondu qui comprend des monomères interpolymérisés de tétrafluoroéthylène, à condition que le copolymère usinable à l'état fondu ne soit pas un copolymère éthylène-propylène fluoré ou une résine de perfluoroalcoxy ; et une seconde couche polymère disposée selon une séquence de répétition avec la pluralité de premières couches optiques, chaque seconde couche optique comprenant un matériau polymère non fluoré choisi dans le groupe constitué par le polyméthacrylate de méthyle ; les copolymères de polyméthacrylate de méthyle ; le polypropylène ; les copolymères de polypropylène ; les polystyrènes ; les copolymères de styrène ; le polychlorure de vinylidène ; les polycarbonates ; les polyuréthanes thermoplastiques ; les copolymères d'éthylène ; les copolymères d'oléfines cycliques ; et leurs combinaisons.
