The copolymer comprises ethylene oxide, —O—CH2—CHR— units in which R is a substituent containing a reactive function which is cross-linkable by free radical process, and possibly —O—CH2—CHR′— units in which R′ is a substituent containing no reactive function which is cross-linkable by means of a free radical process, It is characterized by an excellent polydispersity index I=MW/Mn and a random distribution of the different monomer units. The copolymer is prepared by an anionic copolymerization process. The copolymer is useful for preparing a solid electrolyte having good mechanical properties, a good cationic conductivity and a good chemical compatibility with the electrodes of a generator operating with alkali metals such as lithium and sodium.
