    摘要: A process is disclosed for preparing a poly(phenylene sulfide) (PPS) separation membrane in which a PPS is treated with oxygen to increase its bulk viscosity to at least about 20,000 poise. The treated PPS is then dissolved in a solvent and cast or extruded, followed by a precipitation step.
