摘要： PROBLEM TO BE SOLVED: To provide a separation membrane exhibiting high selectivity and excellent permeability to acid gas. SOLUTION: A coating liquid based on the fluorine-containing polyimide resin, for example, shown by formula 1 and an organic solvent is applied to the surface of a porous support, which is then immersed in a water-based solidifying liquid to form a thin film comprising the fluorine-containing polyimide resin. Such a polar solvent, for example diethylene glycol dimethyl ether or triethylene glycol dimethyl ether, is used as the organic solvent, as has 5.5×10-6 cm2/second self-diffusion coefficient at 25 deg.C when the organic solvent is incorporated in heavy water by 10 wt.%.

摘要： PROBLEM TO BE SOLVED: To enable the ultrafiltration film to secure a high fractionation function and a high transmission flow flux by producing the ultrafiltration film such that a densely porous skin layer consisting of polysulfone resin having a specific range of thickness and a loosely porous layer consisting of the same raw material as the densely porous skin layer form a continuous structure. SOLUTION: This polysulfone ultrafiltration film used for a water treatment, etc., has such a structure that the densely porous skin layer 1 consisting of polysulfone resin having 5nm-1000nm thickness and the loosely porous layer 2 consisting of the same raw material as the densely porous skin layer form a continuous structure. When the porous layer part of both an average densely porous skin layer part having L1 thickness and a loosely porous layer part having L2 thickness which corresponds to L1 ×10 film thickness is observed with a scanning electron microscope by 50,000 magnification and the result is imaged as binary picture with monochromatic picture of 256 gradations, an average luminance ratio (=luminance (L1 )/luminance (L2 )) of the L1 part to the L2 part at 256 gradations is made to be >1.5.
