Abstract
Ионообменная мембрана для получения хлора и щелочи электролизом водного раствора хлорида щелочного металла, состоящая из двух слоев полимера на основе перфторсульфонового эфира с разными эквивалентными весами, отличающаяся тем, что, с целью повышения выхода по току и чистоты целевых продуктов, один из слоев мембраны состоит из полимера с эквивалентным весом 2000 - 30000.An ion exchange membrane for producing chlorine and alkali by electrolysis of an aqueous solution of alkali metal chloride, consisting of two layers of perfluorosulfone ester-based polymer with different equivalent weights, characterized in that, in order to increase the current efficiency and purity of the target products, one of the membrane layers consists of polymer with an equivalent weight of 2000 - 30,000.
