Title
(EN) FLUOROPOLYMER COMPOSITION FOR MULTILAYER ASSEMBLIES
(FR) COMPOSITION DE POLYMÈRE FLUORÉ POUR DES ASSEMBLAGES MULTICOUCHES
Abstract
(EN)
The invention pertains to a composition (C1) comprising: at least one (meth)acrylic modified VDF polymer [polymer (A)] comprising recurring units derived from comprising recurring units derived from vinylidene fluoride (VDF) monomer and at least one hydrophilic (meth)acrylic monomer (MA) of formula (I), wherein each of R1, R2, R3, equal or different from each other, is independently a hydrogen atom or a C1-C3 hydrocarbon group, and ROH is a hydrogen or a C1-C5 hydrocarbon moiety comprising at least one hydroxyl group; at least one inorganic UV blocker compound in an amount not exceeding 5 % wt, with respect to the weight of polymer (A), to multilayer assemblies comprising one layer made from said composition (C1), to a method for manufacturing said multilayer assemblies and to the use of the same in different field of use, including protection of PV modules.
(FR)
L'invention porte sur une composition (C1) comprenant : au moins un polymère de VDF modifié par un monomère (méth)acrylique [polymère(A)] comprenant des motifs récurrents issus du monomère fluorure de vinylidène (VDF) et au moins un monomère (méth)acrylique (MA) hydrophile de formule (I), dans laquelle formule chacun de R1, R2 et R3, identiques aux autres ou différents des autres, représente indépendamment un atome d'hydrogène ou un groupe hydrocarboné en C1-C3 et ROH représente un atome d'hydrogène ou une fraction hydrocarbonée en C1-C5 comprenant au moins un groupe hydroxyle ; et au moins un composé inorganique bloquant les UV en une quantité inférieure ou égale à 5 % en poids, par rapport au poids du polymère (A). L'invention porte également sur des assemblages multicouches comprenant une couche fabriquée à partir de ladite composition (C1) ; sur un procédé pour la fabrication desdits assemblages multicouches ; et sur l'utilisation de ceux-ci dans différents domaines d'utilisation, notamment la protection de modules photovoltaïques (PV).
