Summary Aromatic-aliphatic polyamides were prepared from 2, 5-bis(4-carboxyethylcarbonylphenyl)-3,4-diphenylthiophene (BCDT) with few commercial diamines by using Yamazaki's phosphorylation reaction. The polymers were obtained in good yields and were characterized by solubility tests, viscosity measurements, IR spectroscopy, thermal analysis and X-ray diffraction studies. These polyamides had inherent viscosities in the range of 0.35 to 0.70 dl/g and were amorphous in nature. All the polyamides were readily soluble in solvents such as N,N-dimethylacetamide, N-methyl-2-pyrrolidinone, N,N-dimethylformamide, nitrobenzene, hexamethylphosphoramide, m-cresol, sulphuric acid and did not lose weight below 300°C in air.
