Abstract

COMPOSITIONS ARE DISCLOSED THAT ARE USEFUL FOR PRODUCING A HOMOGENEOUS, SEMIPERMEABLE MEMBRANE, THE COMPOSITION COMPRISING (1) A POLYSULFONE COMPOUND, (2) A SOLVENT, SUCH AS SULFOLANE, ANTYPYRINE, -VALEROLACTAM, DIETHYL PHTHALATE, AND MIXTURES THEREOF, AND (3) A NON-SOLVENT, SUCH AS POLY(ETHYLENE GLYCOL), DI(ETHYLENE GLYCOL), TRI(ETHYLENE GLYCOL), GLYCEROL, AND MIXTURES THEREOF. METHODS ARE DISCLOSED FOR FABRICATING SEMIPERMEABLE MEMBRANES BY HOMOGENEOUSLY MIXING THE COMPOSITION OF THE POLYSULFONE COMPOUND, SOLVENT, AND NON-SOLVENT, MELTING THE COMPOSITION, AND MELT-SPINNING THE MOLTEN COMPOSITION. ALSO DISCLOSED ARE HOMOGENEOUS, MELT-SPUN, SEMIPERMEABLE MEMBRANES USEFUL FOR LIQUID SEPARATION PROCESSES, SUCH AS, BUT NOT LIMITED TO, MICROFILTRATION, ULTRAFILTRATION, DIALYSIS, AND REVERSE OSMOSIS.
