%X The model described in Part I1 has been extended to allow for two factors which may explain the abnormally flat titration curves of some amine ion-exchange resins. They are (a) the possible formation of ion pairs within a resin and (b) a possible increase in the ionization constant of the functional groups in a resin as its degree of ionization increases. It is suggested that the change (b) may occur if the di- electric constant of a resin is increased sufficiently by the absorption of ions and water as titration proceeds.     Calculations have been made of the influence of both effects on thermal regeneration equilibria.
