Abstract: 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.
