We report the ring-opening polymerization of N-alkylated aromatic six-membered ring N-carboxyanhydrides (6-NCA-R) catalyzed by transition metal Schiff base complexes in presence a base. This system allows facile synthesis ortho-aromatic polyamides with high molecular weights via chain-growth polymerization. A mechanism is proposed based on results polymerizations performed under various reaction conditions. Copolymerization 6-NCA-R heterocyclic monomers to prepare heteroatom (N, O, and S) containing copolymers. The thermal properties polymers different N-alkyl side chains were investigated thermogravimetric analysis, differential scanning calorimetry, powder X-ray diffraction.
