## 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
New biphenyl-2,2Π-diyl-containing aromatic polyamides having a crank and twisted noncoplannar structure were synthesized in inherent viscosities of 0.39 -1.42 dL/g by the low-temperature solution polycondensation of 2,2Π-bis(4-aminophenyl)biphenyl, prepared in four steps starting from 2-aminobipheny
