Summary Two inherently coloured polyamides containing aromatic azo unit in their backbone were synthesised from 4,4′-diaminoazobenzene (1) and two aliphatic dicarboxylic acid chlorides (2a, 2b) using N-methyl pyrrolidone (NMP) and N,N-dimethyl acetamide (DMAc) as solvents by the low temperature solution polycondensation method. The polymers were characterised by inherent viscosity, solubility, infra-red and UV-visible spectroscopy. Thermogravimetric analysis of the polymers was carried out to study polymer stability.
