Title (EN) MULTILAYER POLYMERIC REFLECTOR
(FR) RÉFLECTEUR POLYMÈRE MULTICOUCHE
Abstract:
(EN) A multilayer polymeric reflector is provided which comprises: a) a plurality of first optical layers, each first optical layer comprising a polyester having terephthalate comonomer units and ethylene glycol comonomer units, the polyester having a glass transition temperature, where each first optical layer is oriented, and b) a plurality of second optical layers disposed in a repeating sequence with the plurality of first optical layers, each second optical layer comprising a blend of polymethyl methacrylate (PMMA) and polyvinylidene fluoride (PVDF), where the blend has a glass transition temperature less than the glass transition temperature of the polyester comprising the first optical layers, and where the amount of PVDF in the PMMA/PVDF blend is greater than and not equal to about 40% and not more than about 65%. Articles comprising the multilayer polymeric reflector are also provided.
(FR) La présente invention porte sur un réflecteur polymère multicouche qui comporte : a) une pluralité de premières couches optiques, chaque première couche optique comportant un polyester ayant des unités de comonomère de téréphtalate et des unités de comonomère d'éthylène glycol, le polyester ayant une température de transition vitreuse, chaque première couche optique étant orientée, et b) une pluralité de secondes couches optiques disposées en une séquence de répétition avec la pluralité de premières couches optiques, chaque seconde couche optique comportant un mélange de méthacrylate polyméthyle (PMMA) et de polyfluorure de vinylidène (PVDF), le mélange ayant une température de transition vitreuse inférieure à la température de transition vitreuse du polyester comprenant les premières couches optiques, et la quantité de PVDF dans le mélange PMMA/PVDF étant supérieure et non égale à environ 40 % et non supérieure à environ 65 %. La présente invention porte également sur des articles comprenant le réflecteur polymère multicouche.
