<p>A membrane for the separation of an organic solvent from a water-organic solvent mixture has a polymeric membrane (3, 41) of a copolymer consisting essentially of an alpha , beta -unsaturated carbonyl compound as a main monomer. The alpha , beta -unsaturated carbonyl compound includes an acrylic acid ester or a methacrylic acid ester. The polymeric membrane (3, 41) has a crosslinked structure. The polymeric membrane is carried on a support member in the form of a flat membrane (2, 43, 44, 51, 52), a pipe (50) or a hollow fiber (60) . The polymeric member (41) includes particles therein. The polymeric membrane is sandwiched by the support members (43, 44) to form a composite-type separation membrane. The composite-type separation membrane is modulated.</p> |
