Abstract

PURPOSE:To obtain the title separation membrane having high perm-selectivity by converting the porous polymeric membrane matrix obtained by the graft polymerization of acrylamide into its methylol body. CONSTITUTION:Plasma is projected on the porous polymeric membrane consisting of a material such as PP stable to water and alcohol to radically activate the surface of the polymer, an aq. soln. of acrylamide is added, and a reaction is carried out an vacuum. The obtained graft-polymerized membrane of acrylamide is dipped in a soln. obtained by dissolving paraformaldehyde in an aq. sodium hydroxide soln. to cause a reaction, and the graft-polymerized acrylamide layer is converted into its methylol body. The water in a mixed soln. of water and alcohol, or an aq. soln. of ethanol, is selectively permeated through the separation membrane thus obtained by pervaporation, and the water and alcohol are separated.
