The present invention relates to a method for producing a polymer membrane having an isoporous separation active layer, in particular an ultrafiltration membrane or a nanofiltration membrane, and a polymer membrane produced or manufacturable by the present invention. The method according to the invention comprises the step of producing a casting solution comprising at least one solvent, the casting solution comprising at least one amphiphilic block copolymer having at least two different polymer blocks, and at least One of the carbohydrates is dissolved;-spreading the casting solution to form a film;-evaporating near the surface of the at least one solvent during the waiting time; and- Precipitating the film by immersing the film in a precipitation vessel containing at least one non-solvent for the polymer. |
