Abstract
In order to prepare new polyamides with enhanced thermal stability and high solubility in common organic solvents, new diamine monomers containing a pyridine ring bearing several kinds of aromatic type pendant groups on its 4-position were introduced and fully characterized by IR, NMR and mass spectroscopies. Optimal conditions for polyamidations were obtained via study of the model compounds. The polymers were fully characterized by IR, NMR spectroscopies and elemental analysis. The physical properties of the polymers were studied. All of these new polymers show excellent thermal stability and very good solubility in polar aprotic solvents.
