Abstract

Abstract Twelve novel intrinsically colored wholly aromatic azopolyamide-hydrazides containing various proportions of para-and meta-phenylene units were successfully synthesized by a low temperature (− 10 C) solution polycondensation reaction of either 4- amino-3-hydroxybenzhydrazide (4A3HBH) or 3-amino-4-hydroxybenzhydrazide (3A4HBH) with an equimolar amount of either 4, 4'-azodibenzoyl chloride (4, 4'ADBC), 3, 3'- ...
