PURPOSE:To obtain permselective membrane having both high permeability and high selectivity by laminating a monomolecular condensed film of high molecular Schiff base metallic complex comprising recurrent units expressed by the specified formula on a supporting body. CONSTITUTION:A Schiff base cobalt complex I is obtd. by, for example, allowing salicylaldehyde to react with diethylenetriamine in isopropanol, and adding thereafter KOH and cobalt acetate. A soln. of the complex I in dimethylformamide is dropped into a soln. of octadecene/maleic anhydride copolymer in benzene to cause reaction and a high molecular Schiff base metallic complex II comprising the recurrent units expressed by the formula I is obtd. A soln. of the complex II in a mixed solvent comprising benzene and dimethyl formamide is dropped onto the water surface to form thin film, which is laminated on a supporting body such as a porous membrane comprising polyethylene coated with a thin coated layer of silicone polymer. Obtd. compound membrane is effective for production of O2-rich air, etc.
