摘要：
A membrane for the separation of an organic solvent from a water-organic solvent mixture has a polymeric membrane 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 has a crosslinked structure. The polymeric membrane is carried on a support member in the form of a flat membrane, a pipe or a hollow fiber. The polymeric member includes particles therein. The polymeric membrane is sandwiched by the support members to form a composite-type separation membrane. The composite-type separation membrane is modulated.
