The present invention concerns polymers obtained by anionic initiation and bearing functions that can be activated by cationic initiations that are not reactive in the presence of anionic polymerization initiators. The presence of such cationic initiation functions allow an efficient cross-linking of the polymer after molding, particularly in the form of a thin film. It is thus possible to obtain polymers with well-defined properties in terms of molecular weight and cross-linking density. The polymers of the present invention are capable of dissolving ionic compounds inducing a conductivity for the preparation of solid electrolytes.

The present invention is concerned with novel ion-exchange membranes, their method of preparation and their uses. The membranes are made of a polymer obtained from a monomer or a mixture of bifunctional monomers of general formula [T-SO&#x2014;Y&#x2014;SO-T']M. The polymers are useful in an alkali-chloride electrolysis process, as a separator in an electrochemical preparation of inorganic and organic compounds, as a separator between an aqueous and an organic phase, or as a catalyst for Diels-Alder additions, Friedel-Craft reactions, aldol condensations, cationic polymerizations, esterifications, and acetal formations.
