Membranes for gas separation synthesized from polyimides containing 4-fluoro-4′,4″-diaminotriphenylmethane

The present invention relates to the synthesis of linear aromatic polyimides and the production of membranes for the separation of gases. Specifically, polyimides featuring in their chemical structure, in the part derived from a diamine, 4-fluoro-4′,4″-diaminotriphenylmethane, and an aromatic dianhy...
