CA 2351779

The present invention provides crosslinked sulphonic fluorinated ionomers having an equivalent weight 380-1300 g/eq. comprising (A) monomeric units derived from one or more fluorinated monomers containing at least one ethylene unsaturationl; and (B) fluorinated monomeric units containing sulphonyl groups -SO2F in an amount such as to give the above indicated equivalent weight. The ionomers may be used for the preparation of membranes working from room temperature to high temperatures, of the order of 120°C- 180°C, in electrolytic applications.

Dans la présente invention, on divulgue des ionomères sulfoniques fluorés, réticulés, ayant un poids équivalent de 380-1300 g/éq. et comprenant (A) des unités monomères dérivées d'un ou plusieurs monomères fluorés contenant au moins une liaison éthylénique et (B) des unités monomères fluorées contenant des groupes sulfonyles -SO2F en quantité telle qu'il faut pour obtenir le poids équivalent susmentionné. Ces ionomères peuvent être utilisés pour la préparation de membranes utilisables de la température ambiante à haute température, de l'ordre de 120 à 180 degrés C, pour des applications électrolytiques.
