Abstract: 

Three new poly Schiff bases were synthesized by polycondensation of diethylentriamine, 1,2-diaminopropane and o-diaminobenzene with 5a, 10b - dihydrobenzofuro [2,3-b] benzofuran-2,9 - dicarbaldehyde II. The polymers have been characterized by their FT-IR and 1HNMR spectra.The relationship of thermal stabilities of these polymers to their chemical structures was studied by thermogravimetric analysis (TGA) and differential Scanning calorimetry (DSC). Their average molecular weight was determined by GPC. These Schiff base polymers are soluble in common organic solvents. The poly Schiff base III copper complex was prepared and charaterized by FT-IR and UV/vis. The polymer chelate was insoluble in common organic solvents.
