Synthesis and characterization of polyamides containing s‐triazine rings in the main chain

Abstract

AbstractPolyamides were synthesized from diacids containing a s‐triazine ring and two aromatic diamines, namely 4,4′‐diaminodiphenyl ether (ODA) and 4,4′‐diaminodiphenylmethane (MDA), by direct polycondensation using the phosphorylation reaction. Polymers thus obtained were characterized by viscosity measurement, IR spectroscopy, thermogravimetry, X‐ray diffraction, and solubility tests. These polyamides had inherent viscosities in the range of 0.51–0.77 dL/g, and were amorphous in nature. All the polymers were readily soluble in various organic solvents and did not lose weight below 270°C in air.
