چکیده مقاله :

In this paper, an efficient method for synthesis of aromatic polyesters containing schiff base units is described by preparation of two polyesters. These polyesters have been prepared by the reaction of terephthaloyl dichloride on Schiff bases derived from p-hydroxybenzyldehyde and 4,4-diamino diphenyl ether, 4,4-diamino diphenyl methane. The Polymers were characterized by IR, CHNS, thermal analyses (TGA) and viscosities. Inherent viscosities of polyesters were in the range of 0.28-0.31 dLg-1 and thermal stability determined by TGA in nitrogen atmosphere.
