Abstract
1. Композиция для изготовления ионообменной мембраны, включающая фторсодержащий ионообменный полимер и политетрафторэтилен, отличающаяся тем, что, с целью увеличения выхода по току и механических свойств мембраны на ее основе, в качестве фторсодержащего ионообменного полимера она содержит сополимер тетрафторэтилена и сульфированного перфторвинилового эфира и дополнительно содержит поверхностно-активное вещество общей формулыгде Xи X- H, F, Cl;Y - щелочной металл; Н, NH;q = 0,1,2,при следующем соотношении компонентов, вес.%:Ионообменный полимер - 44 - 98,5Политетрафторэтилен - 1,0 - 50,0Поверхностно-активное вещество - 0,5 - 62. Способ получения композиции для изготовления ионообменной мембраны путем смешения фторсодержащего ионообменного полимера с тетрафторэтиленом, отличающийся тем, что, с целью увеличения выхода по току и механических свойств мембраны на основе полученной композиции, политетрафторэтилен используют в виде дисперсии в растворителе, растворяющем поверхностно-активное вещество, указанную дисперсию предварительно гомогенизируют с поверхностно-активным веществом и смешение ведут при температуре плавления полимеров.1. Composition for the manufacture of ion-exchange membrane, including fluorine-containing ion-exchange polymer and polytetrafluoroethylene, characterized in that, in order to increase the current efficiency and mechanical properties of the membrane based on it, it also contains a fluorine-containing ion-exchange polymer surfactant of the general formula where X and X- H, F, Cl; Y is an alkali metal; H, NH; q = 0,1,2, in the following ratio of components, wt.%: Ion-exchange polymer - 44 - 98.5 Polytetrafluoroethylene - 1.0 - 50.0Surfactant - 0.5 - 62. Method of obtaining the composition For the manufacture of an ion-exchange membrane by mixing a fluorine-containing ion-exchange polymer with tetrafluoroethylene, characterized in that, in order to increase the current efficiency and mechanical properties of the membrane based on the resulting composition, polytetrafluoroethylene is used as a dispersion in a solvent that dissolves the surface-active substance indicated by the dispersion this very preliminarily homogenized with a surfactant and mixing is carried out at a temperature of polymer melting.
