摘要：

Polymer precipitation curves for the ternary systems polysulfone/solvent/water and polyethersulfone/solvent/water were determined by a titration method. Membrane forming solvents used were NMP, DMAc, DMF, DMSO, TMU and DMPU. Solvent/water theta-compositions were also estimated. Tie-line data for PES/NMP/H2O system are presented, from which its binodal curve can be constructed.
