Abstract

Two new aromatic–aliphatic polyamides containing azo linkage in the main chain based on 2,2′‐dimethyl‐4,4′‐diaminoazobenzene and adipic/2‐chloro‐5‐methyl‐1,2‐dioic acid (α‐chloro‐δ‐methyl adipic acid) were synthesized and analyzed by thermogravimetry and films were cast. Also three polymers obtained from condensation of 4,4′‐azodibenzoic acid/adipic acid and 2,2′‐bis [4‐(p‐amino phenoxy) phenyl] propane/4,4′‐diaminoazobenzene were studied in terms of mechanical and morphological properties. Film studies were carried out interms of tensile property, scanning electron microscope, dielectric, microwave, and X‐ray diffraction pattern. Thermal studies have been done using thermogravimetric analysis, differential thermal analysis, and pyrolysis‐mass spectral data. The results were correlated with structure and orientation of the molecules. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 1305–1316, 2004
