摘要：
According to the present invention, an aromatic polysulfone resin is offered which is suitable as film material, especially in porous membranes. The aromatic polysulfone resin of the present invention has a reduced viscosity of 0.55-0.65 dL/g, and preferably 0.58-0.62 dL/g, number average molecular weight (Mn) of 22000 or more, and preferably 23500 or more, and a value of the ratio of weight average molecular weight (Mw) relative to number average molecular weight (Mn) of 2.54 or less, and preferably 2.50 or less.
