The invention relates to ionic conductive polymers represented by the general formula
wherein Rp is a residue of a polymer of a compound having a polymerizable unsaturated bond, Q is an organic residue of valence n+1 and connected directly or through another group to Rp by means of a single bond, Mk+ is a cation of valence k, Z is an organic functional group capable of forming an ionic bond with the cation Mk+ or an organic functional group having a coordination capability with Mk+, and m, n and k are integers of 1 or more. The invention further relates to intermediates of the above polymers, methods for their preparation and to batteries, particularly lithium batteries, comprising the polymers as solid electrolytes.
