Synthesis of polyamides containing 4,4′-azodibenzamido units
Authors:Mannarsamy Balasubramanian  Moola Joghee Nanjan  Muchi Santappa
Abstract:
Four coloured polyamides containing azo-p-phenylene units were synthesised from 4,4′-azodibenzoic acid and four aromatic diamines employing both interfacial and solution polymerization procedures. The polymers were characterized by their UV and IR spectra, by inherent viscosity measurements and by solubility data. The stability in conc. sulfuric acid and the thermal behaviour are discussed.
