Volume behaviours of 2-acryloyloxyethyl acid phosphate monopolymer gels immersed in methanol water, acetonitrile-water, tetrahydrofuran-water, dioxane-water and dimethylsulfoxide-water mixtures were examined. Polymer gel samples of the same composition but differing in overall concentration all exhibited a discontinuous volume change at an appropriate solvent composition, regardless of change in gel concentration. This could be accounted for by an unchanged interaction between the polymer gel at various concentrations and a solvent mixture at each transition point.
