Abstract

Two kinds of aromatic, unsymmetrical diamines with ether–ketone group, 3-amino-4′-(4- amino-2-trifluoromethylphenoxy)-benzophenone and 4-amino-4′-(4-amino-2- trifluoromethylphenoxy)-benzophenone, were successfully synthesized with two different synthetic routes. Then, they were polymerized with 4, 4′-oxydiphthalic anhydride, 3, 3′, 4, 4′-benzophenone tetracarboxylic dianhydride, and 2, 2′-bis (3, 4-dicarboxyphenyl)- ...
