ABSTRACT:
An acid diffusion-dialysis membrane, which can be used for separating an acid from a mixture of an acid and a salt, or a mixture of an acid and a water-soluble organic compound, e.g., glucose, by non-electrolytic dialysis, is prepared by forming a film from the combination of (I) a vinyl group containing benzene monomer or a vinyl group containing pyridine monomer, (II) a non-conjugated divinyl-containing monomer, and (III) a thermoplastic polymer which is swellable or soluble in the monomer mixture, polymerizing said monomer mixture in the film, and then introducing anion exchange groups into the resulting polymerized product. The acid diffusion-dialysis membrane is characterized by a high acid diffusion-dialysis coefficient and a high acid-salt selectivity ratio, and further by a relatively high mechanical strength.
