Abstract
PURPOSE: To obtain the separating membrane which is superior in water permeability and mechanical strength by dissolving polysulfone resin and epoxy resin into a polar organic solvent and flow-casting the same to membrane-form or pipe-form then dipping the same into water.
CONSTITUTION: Polysulfone resin is mixed with, for example, epoxy resin of a softening point of preferably 40°C or more corresponding to 1% thereof and the mixture is dissolved in a polar organic solvent such as N-methyl-2-pyrolidone or the like and is subjected to wet type filming by conventional methods. Since this solution does not cause any white clouding and precipitation, the separating membrane formed retains the required mechanical strength without decreasing water permeability.
