Abstract
Two new polyesters were synthesized via polycondensation using Schiff base monomer, 2,3-bis[(4-hydroxybenzylidene)amino]maleonitrile with sebacoyl chloride and terephthaloyl chloride. Both the monomer and polyesters were characterized by FT-IR and 1H NMR. The solubility of the polyesters was examined with various solvents. The number average molecular weight (Mn), weight average molecular weight (Mw) and polydispersity index were determined by gel permeation chromatography. The DSC curves were obtained from differential scanning calorimeter in a dynamic nitrogen atmosphere.
