FIELD: chemistry.
SUBSTANCE: method of modifying anion-exchange membranes involves treatment of a membrane made from a polymer containing secondary and tertiary amine groups with an acid solution and then with a solution of a copolymer of acrylonitrile with dimethyldiallylammonium chloride until formation of quaternary amine groups.
EFFECT: method of modifying anion-exchange membranes containing quaternary amine groups, capable of stable functioning in electrodialysis apparatus at current value considerably higher than the maximum value, and at high pH values of the treated solution.
