Synthesis and Characterization of Polysalicylaldehyde (PSA) by Oxidative Polycondensation of Schiff base Compound [(2,4-dichlorophenylimino)methyl]-phenol

In this paper, polysalisylaldehyde (psa) has been synthesized from the oxidative polycondensation (op) of 2-[(2,4-dichlorophenylimino)methyl]-phenol (sal-2,4-clan) with naocl in an aqueous alkaline medium between 50 and 90°c and characterized by 1h-nmr, ft-ir, uv-vis and tga/dta techniques. the conversion of psa was 61.23% in optimum conditions such as [sal-2,4-clan]0 = 0.02, [koh]0= 0.1 [naocl]0 = 0.12 mol/l at 90°c for 10 h. additionally, the crystal structure of sal-2,4-clan has been determined by single-crystal x-ray crystallography.
