ABSTRACT:
A process for producing dense membranes comprises allowing a solution comprising a polar polymer and/or a polar prepolymer in a polar solvent which is substantially soluble in a polar liquid to spread out over the surface of the polar liquid and allowing the spread out solution to desolvate. The dense membranes can be applied in supported membranes for use in gas separation processes.
