Abstract

a. Procédé de soudage d'une membrane échangeuse de cations en polymère fluoré. b. Ce procédé comprend le soudage par fusion d'une partie de la membrane échangeuse de cations en copolymère fluoré, sous une forme qui renferme des groupes d'échange d'ions -COOY dans lesquels Y représente un atome d'hydrogène ou un groupe alkyle en C1 -C 20 , lorsqu'on utilise la membrane échangeuse de cations sous une forme qui renferme des groupes d'échanges d'ions -(COO)m X dans lesquels X représente un métal alcalin, un métal alcalinoterreux ou NHR1 R2 R3 et R1 , R2 et R3 représentent respectivement chacun un atome d'hydrogène ou un groupe alkye inférieur et m est égal à la valence de X. c. Ce procédé permet de réparer la membrane lorsqu'il se produit des trous d'épingles ou une rupture.
