<p>Oxygen-permeable polymeric membranes to be used in processes for producing oxygen- or nitrogen-enriched air for industrial, medical, and other applications are characterized by a complex comprising (a) a transition metal (II) ion, (b) a ligand comprising a meso-tris( alpha , alpha , alpha -o-substituted-amidophenyl)-mono-( beta -o-substituted amidophenyl)porphyrinato, said metal ion and porphyrin being of the formula (I) <CHEM> in which M stands for a transition metal (II), R's are a substituent each, being acetyl, acryl, methacryl, or pival, and (c) an aromatic amine polymer.</p> |
