COMPOSITION FOR FORMING POLYMERIC FUNCTIONAL MEMBRANE, POLYMERIC FUNCTIONAL MEMBRANE AND PRODUCTION PROCESS THEREFOR, SEPARATION MEMBRANE MODULE, AND ION EXCHANGER

摘要

A composition for forming polymeric functional membranes that comprises component A which comprises a monomer having an acid dissociation constant pKa of a and containing an anionic functional group, component B which comprises a monomer having an acid dissociation constant pKa of b that is greater than a and containing an anionic functional group, and component C which is a photopolymerization initiator represented by the following formula PI-1 or PI-2. The difference between b and a is 1.5-10 and the ratio of the content in terms of molar equivalent of the anionic functional groups of component A to the content in terms of molar equivalent of the anionic functional groups of component B is 90:10 to 50:50.
