    摘要： Ultrathin membranes for separating substances are obtained by exposing shaped articles comprising a water-soluble polymer or a mixture of a water-soluble polymer and water-insoluble polymer to a plasma of a gas selected from helium, argon, nitrogen, hydrogen, oxygen, carbon monoxide, carbon dioxide, ammonia, a hydrocarbon having 1 to 10 carbon atoms, an epoxide having 2 to 10 carbon atoms, or an alkylamine, or a mixture of these substances to crosslink the surface layer, and then washing the exposed articles with water to remove the unreacted portions. The membrane exhibits outstanding performance characteristics when used in the processes for separating or concentrating substances, such as reverse osmosis, ultrafiltration, and the like.

    摘要： A novel phosphorylated cellulose ester membrane containing 0.1 to 10% of phosphorus and having a selective permeability. This permselective phosphorylated cellulose ester membrane consists essentially of a phosphorylated cellulose ester obtained by reacting a phosphorylating reagent such as phosphorus oxychloride with a lower aliphatic acid ester of cellulose, which has a reactive hydroxyl group, in an organic solvent, and then hydrolyzing the resulting ester. The membrane can be used widely in separating materials by processes such as reverse osmosis, ultrafiltration, dialysis, electrodialysis, and the like.
