Abstract

Procédé de production d'une membrane échangeuse de cations. Il comprend l'imprégnation d'une membrane échangeuse de cations en polymère fluoré comprenant un ou plusieurs types de groupes d'échange de cations présentant une acidité inférieure à celle du groupe acide sulfonique, à l'aide d'un dérivé diénique comprenant un groupe acide carboxylique et/ou un groupe transformable en groupe acide carboxylique; la polymérisation partielle du dérivé diénique, puis le gonflement de la membrane dans un solvant organique et le chauffage de la membrane ; et si on utilise un derivé diénique comprenant un groupe transformable en groupe acide carboxylique, la transformation dudit groupe du polymère en groupe acide carboxylique. Electrolyse des halogénures du métal alcalin.A process for producing a cation exchange membrane. It comprises the impregnation of a fluoropolymer cation exchange membrane comprising one or more types of cation exchange groups having an acidity lower than that of the sulfonic acid group, using a diene derivative comprising a group carboxylic acid and / or a group convertible into a carboxylic acid group; partial polymerization of the diene derivative, followed by swelling of the membrane in an organic solvent and heating of the membrane; and if a diene derivative comprising a group convertible to a carboxylic acid group is used, converting said group of the polymer to a carboxylic acid group. Electrolysis of alkali metal halides.
