<P>PROBLEM TO BE SOLVED: To provide an ion exchange spacer imparted with ion exchange group, and to provide a method for producing the ion exchange spacer more easily and inexpensively than conventional methods. <P>SOLUTION: The method for producing the ion exchange spacer comprises impregnating a meshy polymeric base material with a polymerizable composition consisting mainly of a polymerizable monomer having ion exchange group or functional group capable of introducing such ion exchange group, a crosslinking agent and a polymerization initiator, polymerizing the polymerizable monomer, and as necessary, introducing the ion exchange group into the resultant polymer. The ion exchange spacer obtained by the above method is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
