Abstract

N‐Phenylated aromatic polyamide‐esters with high molecular weights were synthesized by the high‐temperature solution polycondensation in nitrobenzene at 200°C from combinations of m‐ and p‐anilinophenol and isophthaloyl and terephthaloyl chloride. Reaction variables such as monomer concentration, solvent, temperature, and time were studied to optimize the reaction conditions for the preparation of high molecular weight polymers. Some of the N‐phenylated aromatic polyamide‐esters have glass transition temperatures around 190°C and good solubility in chlorinated and amide solvents. These polymers gave transparent flexible films by solution‐casting. Copolymers from p‐anilinophenol and the two diacid chlorides were also synthesized and characterized.
