Abstract:
The invention relates to a process for producing a polymer membrane, the polymer membrane being produced from a solution, in particular a casting solution, comprising at least one first polymer. The invention further relates to a polymer membrane. The process of the invention is distinguished by the fact that a water-soluble second polymer and/or oligomer that forms phases in the solution is part of the solution. The polymer membrane of the invention, preferably produced by the process of the invention, has an oil flow rate, in particular of a refined edible oil, of greater than 200 l/m2 h bar at 60° C.
