Production of microporous membrane |
| abstract |
PURPOSE:To obtain the titled polysulfone microporous membrane having excellent water permeability by forming the membrane from a soln. of 5-50wt% polysulfone and 0.1-60wt%, based on the polysulfone, sulfonated polysulfone in a polar org. solvent. CONSTITUTION:From 5 to 50wt% polysulfone not having a dissociable group and 0.1-60wt%, based on the polysulfone, sulfonated polysulfone are dissolved in a polar org. solvent. The sulfonation rate of the sulfonated polysulfone is preferably controlled to 0.1-4. A solvent dissolving polysulfone and soluble in water is used as the solvent. The soln. is cast on a glass sheet in 150mu liq. thickness, the sheet is immersed in water as the coagulating liq. and the polysulfone membrane is obtained. |
