Title
(EN) MULTILAYERED POLYOLEFIN-BASED FILMS HAVING A LAYER COMPRISING A CRYSTALLINE BLOCK COPOLYMER COMPOSITE OR A BLOCK COPOLYMER COMPOSITE RESIN
(FR) FILMS MULTICOUCHES À BASE DE POLYOLÉFINE COMPORTANT UNE COUCHE COMPRENANT UN COMPOSITE DE COPOLYMÈRE SÉQUENCÉ CRISTALLIN OU UNE RÉSINE COMPOSITE DE COPOLYMÈRE SÉQUENCÉ
Abstract
(EN)
Disclosed are multilayer film structures comprising a layer (B) that comprises a crystalline block copolymer composite (CBC) or a specified block copolymer composite (BC), comprising i) an ethylene polymer (EP) comprising at least 80 mol % polymerized ethylene; ii) an alpha-olefin- based crystalline polymer (CAOP) and iii) a block copolymer comprising (a) an ethylene polymer block comprising at least 80 mol % polymerized ethylene and (b) a crystalline alpha-olefin block (CAOB); and a layer C that comprises a polyolefin having at least one melting peak greater than 1255C, the top facial surface of layer C in adhering contact with the bottom facial surface of layer B. Such multilayer film structure preferably comprises (A) a seal layer A having a bottom facial surface in adhering contact with the top facial surface of layer B. Such films are suited for use in electronic device (ED) modules comprising an electronic device such as a PV cell. Also disclosed is a lamination process to construct a laminated PV module comprising such multilayer film structures.
(FR)
La présente invention se rapporte à des structures de films multicouches comprenant une couche (B) qui comprend un composite de copolymère séquencé cristallin (CBC) ou un composite de copolymère séquencé (BC) spécifié, comprenant i) un polymère d'éthylène (EP) comprenant au moins 80 % en moles d'éthylène polymérisé ; ii) un polymère cristallin à base d'alpha-oléfine (CAOP) et iii) un copolymère séquencé comprenant (a) une séquence de polymère d'éthylène comprenant au moins 80 % en moles d'éthylène polymérisé et (b) une séquence cristalline d'alpha-oléfine (CAOB) ; et une couche C qui comprend une polyoléfine ayant au moins un pic de fusion supérieur à 1255 C, la surface faciale supérieure de la couche C étant en contact adhérant avec la surface faciale inférieure de la couche B. Une telle structure de films multicouches comprend de préférence (A) une couche d'étanchéité A ayant une surface faciale inférieure en contact adhérant avec la surface faciale supérieure de la couche B. De tels films sont appropriés pour être utilisés dans des modules de dispositif électronique (ED) comprenant un dispositif électronique tell qu'une cellule PV. L'invention se rapporte également à un processus de stratification pour construire un module PV stratifié comprenant de telles structures de films multicouches.
