A new aromatic dicarboxylic acid, 1,4-bis(p-carboxyphenoxy)naphthyl (3), was synthesized by the reaction of p-fluorobenzonitrile with 1,4-naphthalenediol, followed by hydrolysis. Aromatic polyamides having inherent viscosities of 1.27-2.22 dL/ g were prepared by the triphenyl phosphite activated pol
## Abstract Aromatic polyamides (aramids) having inherent viscosities of 0.3β1.6 dL/g were prepared by the direct polycondensation of 4,4β²βsulfonyldibenzoic acid with various aromatic diamines using triphenyl phosphite and pyridine as condensing agents. Aromatic polyesters (polyarylates) with inher
