The cloud point curves for polysulfone (PSf)/solvent/water systems were determined by a titration method. A small amount of water was needed to induce liquid-liquid demixing and the temperature effect was small. From numerical calculations, it was found that the binary interaction parameters for the
To construct a phase diagram of the polysulfone (PSF)/polyethersulfone (PES)/N-methyl-2-pyrrolidone (NMP)/water quaternary system, cloud point measurements were carried out by a titration method. The miscible region in the PSF/PES/ NMP/water quaternary system was narrow compared to the PSF/NMP/water
