Abstract
Способ получения анионообменных мембран, содержащих четвертичные аминогруппы, отличающийся тем, что мембраны, содержащие первичные и/или вторичные, и/или третичные аминогруппы, обрабатывают кислотой до полного протонирования аминогрупп, а затем обрабатывают раствором органического модифицирующего агента, являющегося полифункциональным соединением, содержащим карбоксильные группы и радикалзамещенные четвертичные аминогруппы, до образования в модифицируемой мембране четвертичных аминогрупп. A method of producing anion exchange membranes containing quaternary amino groups, characterized in that membranes containing primary and / or secondary and / or tertiary amino groups are treated with acid until the amino groups are fully protonated, and then treated with a solution of an organic modifying agent, which is a multifunctional compound containing carboxyl groups and radical substituted quaternary amino groups, before the formation of quaternary amino groups in the modified membrane.
