ملخص المقالة :

In this article six new copoly(amide-imide)s (11a-c) were synthesized through the directpolycondensation reaction of 1,3-bis[4,4'-(trimellitimido) phenoxy] propane (6) with 3,3'-diamino diphenyl sulfone (7), 4,4'-diaminodiphenyl ether (8) and 1,5-naphtalene (9) in thepresence of fumaric acid (10) as a second diacid in a medium consisting of N-methyl-2-pyrrolidone, triphenyl phosphite, calcium chloride and pyridine. The resulted polymers werefully characterized by means of FT-IR spectroscopy, elemental analyses, inherent viscosity, andsolubility tests. Thermal stabilities of a polymer (11a-c) were investigated by using TGA & DTGthermograms.
