FIELD: chemistry. ^ SUBSTANCE: cation-exchange membrane for electrolysis which includes a fluoropolymer which contains an ion-exchange group and a porous base is distinguished by that, on the surface of the anode side of the membrane there are projecting parts with a fluorine-containing polymer which contains an ion-exchange group; 20ëñhëñ150, where h is the average height (mcm) from the surface of the anode side of the membrane to the top of the projecting parts; 50ëñPëñ1200, where P is distribution density (number/cm2) of the projecting parts; 0.001ëñSëñ0.6, where S is the ratio of area of the bottom surfaces of the projecting parts to the total area of the anode side of the membrane; and Tëñ0.05, where T is the ratio of the area of the top parts of the projecting parts to the total area of the anode side of the membrane. ^ EFFECT: invention enables obtaining a membrane with stable operational characteristics with retention of electrochemical properties and mechanical strength. ^ 9 cl, 1 tbl, 7 ex |
