Recently Jam showed that the thermodynamic properties of ion-exchange resins could be evaluated by consideration of macro- and small-ion interaction in the gel phase (3–5). Good agreement was obtained between the pH values of the basic monomer units and the intrinsic pK values calculated for cross-linked polymethacrylic acid and the acid-form of the cross-linked Dowex Chelating A-l resin, a polystyrene, divinyl benzene copolymer containing iminodiacetic acid functional groups attached to the hydrocarbon matrix. In the calculation it was assumed, without detriment, that interaction between neighboring functional groups was negligible and that the cross-linked polymer was sufficiently homogeneous to support symmetry approximations.
