Abstract

PURPOSE:To manufacture semipermeable membrane shown in the title having excellent separating power through flowing and extending of a membrane-manufacturing solution made by addition of ester of oxycarboxylic acid and alcohol, both of which do not dissolve the cellulose acetate, to cellulose acetate of specific degree of acetylation, a material for making membrane.
