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

A new diamine 5,5 '-bis[4-(4-aminophenoxy)phenyl]-hexahydro-4,7-methanoindan (3) was prepared through the nucleophilic displacement of 5,5'-bis(4-hydroxylphenyl)-hexahydro-4,7-methanoindan (1) with p-halonitrobenzene in the presence of K 2 CO 3 in N,N-dimethylformamide (DMF), followed by catalytic r
A diimide dicarboxylic acid, 1,4-bis(4-trimellitimidophenoxy)naphthalene (1,4-BTMPN), was prepared by condensation of 1,4-bis(4-aminophenoxy)naphthalene and trimellitic anhydride at a 1 : 2 molar ratio. A series of novel poly(amide-imide)s (IIa-k) with inherent viscosities of 0.72 to 1.59 dL/g were
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 An imide ring‐containing dicarboxylic acid, 3,3‐bis[4‐(4‐trimellitimidophenoxy)phenyl]‐1‐oxoisoindoline, was prepared via condensation of 3,3‐bis[4‐(4‐aminophenoxy)phenyl]‐1‐oxoisoindoline and trimellitic anhydride. A series of new aromatic bis(phenoxy)‐1‐oxo‐isoindoline‐containing poly
## Abstract Six new poly(amide‐imide)s **8a–f** containing trimethylene moiety in the main chain were synthesized by the polycondensation reactions of 1,3‐bis[4,4'‐(trimellitimido) phenoxy] propane **6** with six different aromatic diamines **7a–f** in a medium constituting __N__‐methyl‐2‐pyrrolido
