Abstract

The present invention relates to a process for cross-linking a membrane comprising a polyimide, wherein the polyimide is cross-linked with a cross-linking agent comprising two or more isocyanate groups. The present invention also relates to a membrane obtainable by this process and to the use of the membrane in a separation process. The present invention also relates to a process for separating a dissolved component having a molecular weight of about 100 to about10000 Dalton from a solution, said process comprising: (a) contacting the solution with the membrane, and (b) isolating or concentrating the component.
