dc.description.abstractThe Schiff base monomer was synthesized-by the condensation reaction between salicyladehyde and p-phenylendiamine. The Schiff base polymers having double azomethine group were prepared-by oxidative polycondensation (OP) reaction of monomer in aqueous alkaline medium with NaOCl (P-1) and H2O2 (P-2) as the oxidants at 90 degrees C. Cu(II) and Ni(II) complexes of the polymers. were synthesized by the reaction of polymer and metal acetate salts. The monomer and polymers; were characterized by elemental analyses, thermogravimetric analyses, DSC analyses, UV-Vis, FT-IR, H-1 and C-13 NMR spectroscopic studies, which revealed that the P and P-2 polymers synthesized by OP is composed of oxyphenylene (C-O-C; P-1 = 77% P-2 = 75%), phenylene (C-C; P, = 23%, P-2 = 25%) units. Average molecular weights of polymers were determined by gel permeation chromatography. The polymers were soluble in polar aprotic solvents and aqueous alkaline media. According to the thermogravimetric analyses, Schiff base polymer (P,) exhibited excellent thermal stability with 38% residual weight at 1000 degrees C in nitrogen atmosphere. The thermal stability of these polymer systems are found to be in order P-2 > P-1. As the synthesized polymers were soluble in common solvents such as THF, DMF, DMSO, these properties of polymer are-promising for it is environmental and analytical usage.
