  • Solid polymer electrolyte based on cross-linked polyvinylether
    Patent number: 5173205
    Abstract: A solid polymer electrolyte in membrane form, consisting of a solid solution of an ionic compound dissolved in a polyether, is obtained by copolymerizing a vinyl ether with an allyl vinyl ether to obtain a copolymer with allyl unsaturations; hydrosilylating the allyl double bond of this copolymer by reaction with an alkoxysilane to obtain a hydrosilylated copolymer; and cross-linking the hydrosilylated copolymer by means of a diprotic cross-linking agent, operating in solution in an organic solvent in the presence of an ionic compound, and evaporating the solvent to obtain a membrane.
