<p>COMPOSITE DENSE MEMBRANE AND FLUID(S) SEPARATION PROCESS CARRIED OUT THEREWITH Composite dense membrane comprising a dense selective film of a silicon-free polymerizate, a dense highly permeable polymeric intermediate layer formed by conventional polymerization and a microporous substrate supporting the polymerizate film and the intermediate layer. Fluids, e.g. gases may be selectively separated using such a composite dense membrane.</p> |
