Crosslinked polymers and their uses in electrochemical systems, for example, as electrolyte membrane, are described. More precisely, these crosslinked polymers are formed by the crosslinking of a random copolymer based on monomers of glycidyl methacrylate or acrylate and of poly(ethylene glycol) methyl acrylate or methacrylate with a volatile polyamine crosslinking agent.
