Abstract A series of soluble fluorinated polyamides (4a-h) were synthesized from 2- trifluoromethyl-4, 4′-diaminodiphenylether (2) with various aromatic diacids (3a-c) and imide-containing diacids (3d-h) via direct polycondensation with triphenyl phosphite and pyridine. Diamine 2 was prepared through nucleophilic substitution reaction of 2-chloro-5- nitrobenzotrifluoride and 4-nitrophenol in the presence of anhydrous K 2 CO 3 to yield the ...
