## Abstract A new monomer of tetraimide‐dicarboxylic acid (IV) was synthesized by starting from ring‐opening addition of 4,4′‐oxydiphthalic anhydride, trimellitic anhydride, and 1,4‐bis(4‐amino‐2‐trifluoromethylphenoxy)benzene at a 1:2:2 molar ratio in __N__‐methyl‐2‐pyrrolidone (NMP). From this ne
An imide ring-performed dicarboxylic acid bearing one hexafluoroisopropylidene and two ether linkages between aromatic rings, 2,2-bis[4-(4-trimellitimidophenoxy)phenyl]hexafluoropropane (II), was prepared from the condensation of 2,2-bis[4-(4-aminophenoxy)phenyl]hexafluoropropane and trimellitic anh
A new dicarboxylic acid having a kinked structure was synthesized from the condensation of 2,2 -bis (4-aminophenoxy ) biphenyl and trimellitic anhydride. A series of biphenyl-2,2 -diyl-containing aromatic poly ( amide-imide ) s having inherent viscosities of 0.23 -0.94 dL / g was prepared by the tri
