Abstract
PURPOSE:To improve water permeability, consolidation resistance, oxidation resistance and other properties of selective permeability film applied in reverse osmosis method, etc., by crosslinking a specified compound having secondary amino radical and a polyfunctional compound on a porous film. CONSTITUTION:A compound of aliphatic diamine or the like containing only secondary amino radical having active hydrogen atom in one molecule is spread on a supporting film of fine porosity of polysulfone or the like by dissolving in water or an organic polar solvent of methanol or the like miscible with water having a boiling point of 120 deg.C or less. Then, in addition to draining, a pseudo thin film of amine compound is formed. Next, a crosslinking agent having three or more functional groups such as acid halide radicals which form, when reacting with the secondary amino radical in the compound, any of carbonamide, sulfonamide or urea bond is used alone, or combined with functional groups having this functional groups by two or more pieces, to give crosslinking treatment. Thus, a thin film having a selective permeability is formed on the substrate surface.
