The membrane is formed from a casting liquid comprising the polyetherimide together with a solvent and a non-solvent, forming a thin layer of the liquid and extracting at least part of the solvent and non-solvent to form the required membrane. The membrane may be modified by the inclusion of additional chemical moieties.
