Abstract
A solvent of the polymer-salt complex and a non-solvent thereof are added to the solvent used in the polymer synthesis, to provide a lower and an upper phase. The lower phase contains substantially all the polymer in the solvent of the polymer-salt complex. It is separated from the upper phase and the salt is added to the lower phase to constitute a solution of the electrolyte.
