FLUOROCARBON POLYMER MEMBRANE WITH PENDANT CARBOXYLIC ACID GROUPS
摘要
<p>A fluorocarbon polymer and a cation exchange membrane formed of fluorocarbon polymer are characterized by the presence in at least one surface layer of the polymer of pendant carboxylic acid groups of the formula -- OCF2COOM --, where M stands for hydrogen, ammonium, quaternary ammonium or a metal atom.</p>
