SYNTHESIS OF ORGANO SOLUBLE AROMATIC POLY(AMIDE-IMIDE)S BASED ON 2-(5-(3,5-DINITROPHENYL)-1,3,4-OXADIAZOLE-2-YL)PYRIDINE IN AN IONIC LIQUID
the syntheses of new thermally stable poly(amide-imide)s with pendant 2-pyridyl-1

and trimellitic acid anhydride. Polymers were prepared from the reaction of the diimide-diacid (DIDA) and different aromatic diamines in butyl methyl imidazolium bromide
[bmim][Br]
in the presence of triphenyl phosphite (TPP) as condensing agent without needing any extra components. The prepared poly(amide-imide)s were characterized by FTIR
elemental analysis
and through the synthesis of a model compound. The prepared polymers were soluble in polar and aprotic solvents
such as DMF
DMSO
NMP and DMAc. The inherent viscosity of the polymer solutions was in the range of 0.52-1.33 dL/g measured in concentrated H

at a concentration of 0.125 g/dL at (25 ± 0.5)℃. The results are compared with the results obtained from common direct polycondensation with NMP as solvent. Polymers obtained in ionic liquid showed higher inherent viscosity than that of polymers obtained
via
classical method in NMP. Thermal properties of the polymers were studied with DSC and TGA methods.
