## Abstract Four dicarboxylic acids containing one preformed imide ring were prepared by condensation of trimellitic anhydride with α‐amino acids such as glycine, DL‐alanine, DL‐valine, and DL‐lcucinc. These diacids were subsequently directly polycondensated with various aromatic diamines using tri
## Abstract Two imide ring‐bearing dicarboxylic acids, __N,N__′‐[1,4(or 1,3)‐phenylenebis(isopropylidene‐1,4‐phenyleneoxy‐1,4‐phenylene)]diphthalimide‐4‐carboxylic acid (__p__‐4 and __m__‐4), were prepared via condensation of 4,4′‐[1,4(or 1,3)‐phenylenebis(isopropylidene‐1,4‐phenyleneoxy)]dianiline
## SYNOPSIS A series of novel bis(phen0xy)naphthalene-containing polyamides having inherent viscosity up to 2.02 dL/g were synthesized by the direct polycondensation of the diamine 1,7bis(4-aminophenoxy)naphthalene with various aromatic dicarboxylic acids in N-methyl-8-pyrrolidone (NMP) using trip
## 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
