Notes:
The cloud point curves for the ternary systems carboxylated polysulfones/solvent/water were determined by a titration method. Membrane-forming solvents used were NMP, DMAc, DMF, DMSO, TMU, and DMPU. Four modified polysulfones containing 0.43, 0.93, 1.38, and 1.93 carboxyl groups per repeat unit were synthesized for this study. Water/solvent theta-compositions and solubility parameters for these polymers were also estimated.
