      Abstract: A novel fully aromatic diamine   containing highly pyridine units, amide, and ether groups was   prepared via two-step reactions: nucleophilic substitution   reaction of 2,6-diaminopyridine with 6-chloronicotinoyl chloride   led to preparation of a dichloro-diamide compound. Subsequent   reaction of this compound with 5-amino-1-naphthol resulted in   synthesis of the particular diamine. After complete   characterization, polycondensation reaction of the diamine with   different dianhydrides led to preparation of related   poly(amide-ether-imide)s. The polymers were characterized and   their physical and thermal properties including viscosity,   solubility, water absorption, thermal behavior and stability,   flame retardancy, and crystallinity were studied. The   nicotinic-based poly(amide-ether-imide)s showed high heat and   flame resistant, low water absorption in conjunction with   improved solubility in polar solvents. © 2015 Taylor &   Francis.
