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
## Abstract New aromatic diimide‐dicarboxylic acids having kinked and cranked structures, 2,2′‐bis(4‐trimellitimidophenoxy)biphenyl (2a) and 2,2′‐bis(4‐trimellitimidophenoxy)‐1,1′‐binaphthyl (2b), were synthesized by the reaction of trimellitic anhydride with 2,2′‐bis(4‐aminophenoxy)biphenyl (1a) a
A novel polymer-forming diimide-diacid, 2,6-bis(4-trimellitimidophenoxy)naphthalene, was prepared by the condensation reaction of 2,6-bis(4-aminophenoxy)naphthalene with trimellitic anhydride (TMA). A series of novel aromatic poly(amideimide)s containing 2,6-bis(phenoxy)naphthalene units were prepar
