Abstract

PURPOSE: To produce an aromatic polysulfone semipermeable membrane having high filtration efficiency and high permeation rate by using a specific casting solvent and using water as a solidifying bath.
CONSTITUTION: A polysulfone resin consisting of the repetitive units of the formula is dissolved in mixed solns. consisting of 95W40wt% N, N-dimethylformamide, or N-methylpyrolidone, and 5W60wt% dimethylsulfoxide, and left still at room temp., whereby it is defoamed and the homogeneous soln. is obtd. This soln. is cast on a smooth glass plate and is left standing, after which it is immersed together with the glass plate in water. The gelled membrane peeled from the glass plate is recovered.
