Process for preparing improved cation-exchange membranes |
摘要 |
An improved cation-exchange membrane, onto which have been adhered fine particles of a crosslinked high molecular weight substance having anion-exchange groups and which can maintain a specific permselectivity for monovalent cations over a long period of time, is prepared with ease by treating a cation-exchange membrane with a suspension of fine particles of the said crosslinked high molecular weight substance.
