The Schiff bases ligand 4,4’-bis-[(N-O-tolulylsalicylaldiamine-5)azo]biphenyl (H2BTSAB)and its chelate polymers with Cr(III) ,Mn(III), Fe(III) ,VO(IV) Zr(IV) Th(IV) Ti(III) and UO2(V) have been prepared . These have been characterized by elemental analyses, IR and electronic spectra, magnetic susceptibility measurements and thermogravimetric analysis. Thermogravimetric analysis confirms the coordination of H2O in complexes. 1H NMR spectrum of ligand clearly indicates presence of OH and azomethine groups. The ligand act as a bidentate molecules coordinating through phenolic oxygen thermal data have been analysed for the kinetic parameters by using Broido method and activation energy has in the range 33.18 to 80.42 kJmol-1 while the decomposition follows first order kinetics. The 40-2200C and the chelates were found to show semiconducting behavior. The activation energy of the electrical conduction lies in the range 1.233-0.127eV. Oxidation of styrene with selected catalysts was tested using H2O2 as an oxidant.
