## Abstract Summary: A series of novel lyotropic liquid crystalline polyamides derived from 1,2‐dihydro‐2‐(4‐aminophenyl)‐4‐[4‐(4‐(aminophenoxyl)phenyl)]‐phthalazinone (DHPZ‐DA), __p__‐phenylene diamine (PPD) and terephthaloyl dichloride (TPC) have been successfully synthesized by the low temperatu
## Abstract Aromatic polyamides (aramids) having inherent viscosities of 0.3–1.6 dL/g were prepared by the direct polycondensation of 4,4′‐sulfonyldibenzoic acid with various aromatic diamines using triphenyl phosphite and pyridine as condensing agents. Aromatic polyesters (polyarylates) with inher
## Abstract New aromatic polyamides (aramids) having inherent viscosities of 0.5–2.6 dL/g were prepared by the direct polycondensation of 4,4′‐diaminotriphenylamine with various aromatic dicarboxylic acids in __N__‐methyl‐2‐pyrrolidone using triphenyl phosphite and pyridine as condensing agents. Th
