<P>PROBLEM TO BE SOLVED: To provide an ion-exchangeable mixture and its producing method. <P>SOLUTION: The ion-exchangeable mixture contains a polymeric compound consisting of an ion exchange resin, an acrylamide mixture containing at least one of bis-acrylamide and acrylamide, and a copolymer obtained by reacting the polymeric compound with the acrylamide mixture. An ion-exchangeable film produced by using the ion-exchangeable mixture has the electric resistance much lower than that of the conventional ion-exchangeable film, becomes charged electrically and consequently has excellent selective permeability. Since the ion-exchangeable film is produced under very mild conditions, it can be produced easily. Since the ion-exchangeable film is coextensively formed while advancing a cross-linkage reaction in an aqueous solvent, it can be produced freely to have the desired size, shape or figure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
