FLUORINATED POLYMER CATION EXCHANGER MEMBRANE FOR ELECTROLYSIS AND ELECTROLYSIS USING THE SAME

摘要

P A. CATION EXCHANGER IN FLUORINATED POLYMER FOR ELECTROLYSIS AND ELECTROLYSIS WITH THE USE OF THIS MEMBRANE. /P P B. THE MEMBRANE IS OBTAINED BY TREATING A CATION EXCHANGER MEMBRANE, HAVING ION EXCHANGER GROUPS -COOM (M REPRESENTS THE HYDROGEN ATOM OR AN ALKALI METAL ATOM) OR GROUPS CONVERTIBLE IN THESE GROUPS AND HAVING AN ION EXCHANGE CAPACITY OF 0.5 TO 2.0 MEQG OF DRY POLYMER IN A FORM HYDROLYZED, TO OBTAIN A PERCENTAGE OF WEIGHT GAIN (DW) IN THE FOLLOWING AREA: DW 1.6 E 1.7AR AS AN UPPER LIMIT; DW 0.8 E1.7AR AS LOWER LIMIT; AT 0.5 AS A LEFT LIMIT AND AT 0.5 AS A RIGHT LIMIT, REPRESENTED IN FIGURE 1 (LOGARITHMIC SCALE ON THE ORDER), IN AN AQUEOUS MEDIUM OF A BASE OR SALT AT A CONCENTRATION OF 1 AT 20 BY WEIGHT, AT A TEMPERATURE OF 0 TO 60C AFTER HYDROLYSIS OR AT THE SAME TIME AS HYDROLYSIS. /P P C. ELECTROLYSIS OF AN AQUEOUS SOLUTION OF AN ALKALINE METAL CHLORIDE. /P
