Title (EN) A METHOD FOR PRODUCTION OF A CROSS-LINKED POLYMER FILM
(FR) PROCEDE DE PRODUCTION D'UNE COUCHE MINCE DE POLYMERE RETICULE
Abstract:
(EN) A process of producing a cross-linked polymer product (1) by multilayer technique is disclosed, said product incorporating at least one silane group-containing polymer layer (2, 4) cross-linked by means of a catalyst. The cross-linked polymer product consists of a multilayered film. In the process, the catalyst is introduced into a layer (3) at or adjacent the layer or layers (2, 4) to be crosslinked, crosslinking being achieved by diffusion of the catalyst from the catalyst-containing layer (3) into the layer or layers (2, 4) to be crosslinked. The crosslinkable polymer material is a silane group-containing olefin copolymer, such as an ethylene vinyl trimethoxy silane copolymer, or an ethylene/butylacrylate/vinyl trimethoxy silane terpolymer crosslinkable by means of a silanol condensation catalyst, such as a tin carboxylate compound, for example dibutyl tin dilaurate.
(FR) Procédé de production d'un produit (1) polymère réticulé par technique multicouche, ledit produit comportant au moins une couche (2, 4) de polymère contenant un groupe de silanes, réticulée au moyen d'un catalyseur. Le produit polymère réticulé consiste en une pellicule mince multicouche. Dan le procédé, on introduit le catalyseur dans une couche (3) située au niveau de la ou des couches (2, 4) à réticuler ou adjacente à celle(s)-ci, la réticulation étant obtenue par diffusion du catalyseur à partir de la couche (3) contenant celui-ci, dans la ou les couches (2, 4) à réticuler. La matière polymère réticulable est un copolymère d'oléfine contenant un groupe de silanes, tel qu'un copolymère de silane de triméthoxy vinylique d'éthylène, ou un terpolymère de silane triméthoxy d'éthylène/butylacrylate/vinyle, réticulable au moyen d'un catalyseur de condensation au silanol, tel qu'un composé de carboxylate d'étain, par exemple du dilaurate de dibutylétain.
