ION-CONDUCTING THERMALLY CONVERTIBLE POLYMERIC MATERIAL AND POLYMERIZED COMPOUND FOR ITS PRODUCTION Russian patent published in 2004 - IPC

FIELD: solid-state ion conductors or polymeric electrolytes.

SUBSTANCE: proposed compound for producing ion-conducting thermally convertible polymeric materials has in its composition alkyl and/or allyl ester of methacrylic acid that functions as monomer that incorporated in alkyl radical 1 - 16 atoms of carbon and one or more salts of s-, p-, d-, and f-metals of halide-substituted low aliphatic carbonic acid having 1 - 4 atoms of carbon and/or ammonium trifluoroacetate in alkyl radical with low carbonic acids incorporating 1 - 6 atoms of carbon in alkyl radical added or not to them, remaining chelate-forming organic compounds that incorporate heteroatom of nitrogen, or sulfur being added or not to them; in addition it has salts of s- and/or p-metal of alkyl and/or alkenyl-acrylic acid, and/or organic component composed of one or more low-molecular substances each incorporating in its composition at least two functional groups of OH, NH_x, CS, COOH, CO and/or polar solvents capable of dissolving both mentioned salts of halide-substituted low aliphatic carbonic acid and mentioned salts of alkyl and/or alkenyl-acrylic acid, proportion of components being as follows: 1 · 10^-4 - 2 mole/l of monomeric mixture of mentioned salts of halide-substituted low aliphatic carbonic acid; 0.01 - 0.1 mole fractions of salt of s- and/or p-metal of alkyl and/or alkenyl-acrylic acid, or 0.1 - 0.55 mole fractions of mentioned organic components, or mixture thereof; and the rest of monomer of mentioned composition. In addition description is given of ion-conducting thermally convertible polymeric material produced from polymeric compound and ion-conducting polymeric film produced from thermally convertible polymeric material. Transparent ion-conducting material produced in the process has electric conductivity as high as 10^-4 to 10^-5S/cm at room temperature with desired characteristics of material being retained.

EFFECT: enhanced electric conductivity of material, that is enhanced conductivity and stability of gel-electrolyte produced in the process.
