Aromatic Polyimide Membranes with <i>tert</i>-Butyl and Carboxylic Side Groups for Gas Separation Applications—Covalent Crosslinking Study

A set of aromatic copolyimides was obtained by reaction of 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA), and mixtures of the diamines 1,4-bis(4-amino-2-trifluoromethylphenoxy)-2,5-di-<i>tert</i>-butylbenzene (CF<sub>3</sub>TBAPB) and 3,5-diamino benzoic acid (D...
