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.

Abstract: The present invention relates to a process for manufacturing a hollow fibre membrane having a supporting layer and a separating layer, said process comprising: (a)extruding a spinning composition comprising a first polymer and a solvent for the first polymer through an inner annular orifice of a hollow-fibre die; (b)co-extruding a composition comprising an organic nucleophilic reagent and a mixtures of a solvent and a non-solvent for the first polymer, wherein the composition is either extruded through a central annular orifice of the hollow-fibre die or through an outer annular orifice of a hollow-fibre die; and (c)passing the hollow-fibre through a coagulation bath. The hollow fibre membrane according to the present invention can be used in gas separation processes, vapour separation processes and liquid filtration processes.
