<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a composite porous ion-exchanger wherein a member functioning as an ion-exchange membrane and a member functioning as an ion-exchanger having especially large pore volume and specific surface area are integrally formed. <P>SOLUTION: The method for manufacturing the composite porous ion exchanger comprises a step of obtaining a water-in-oil type emulsion by stirring and mixing an oil-soluble monomer not containing ion exchange groups such as styrene, α-methylstyrene, vinyltoluene, vinylbenzyl chloride and divinylbenzene, a surfactant such as sorbitan monooleate, water, and a polymerization initiator, a step of filling the water-in-oil type emulsion in a vessel, of which at least a part of the portion in contact with the water-in-oil type emulsion is made from a hydrophobic material, and polymerizing the water-in-oil type emulsion, and a step of introducing ion exchange groups into the polymer obtained in the previous step. <P>COPYRIGHT: (C)2007,JPO&INPIT |
