Abstract

PURPOSE:To obtain a hollow yarn composite membrane which is high in both degree of desalting and amount of water permeation with a simple method by using copolyamide consisting of specified constitutional units and dissolving it into a solvent in which aromatic polysulfone is not dissolved and applying this soln. on a porous supporting material consisting of a aromatic polysulfone. CONSTITUTION:Copolyamide which mainly includes the constitutional units shown in the general formulas 1, 2 in molar ratios of 95/5-35/65 is synthesized by allowing diamine component such as diaminodiphenylsulfone and aminobenzoic acid to react with aromatic dicarboxylic acid halide such as isophthalic acid chloride. A coating agent is obtained by dissolving it into a solvent which is a non-solvent for a supporting material e.g. into methyl cellosolve. After immersing a porous hollow yarn supporting material consisting of aromatic polysulfone into the coating agent, it is dried to remove the solvent and a permselective hollow yarn composite membrane wherein the surface of the supporting material is coated with copolyamide in thickness not more than 10mum is obtained.
