چکیده
|
Three polyesters have been prepared by the reaction of terephthaloyl chloride on schiff bases derived from 4- hydroxybenzyldehyde and meso- stilbenediamine,ethylenediamine or 4- nitrophenylenediamine.the polymers were obtained in good yield (85% theoritical) and were characterized by c,h,n elemental analyses,ft-ir,uv and visible spectroscopy and thermal analyses (tga,dta). the results obtained were compared with that of schiff base monomers .the viscosities measurements of the polyesters and their schiff base monomers supported the polymers formation.
