SYNTHESIS, CHARACTERIZATION AND THERMAL STUDIES OF POLYCHELATES DERIVED FROM 2-HYDROXYACETOPHENONE THIOUREA TRIOXANE RESIN

Polychelates of copper(II), nickel(II), cobalt(II), manganese(II), zinc(II), oxovanadium(IV) and dioxouranium(VI) with 2-hydroxyacetophenone-thiourea-trioxane resin have been synthesized. Elemental analyses of the polychelates indicate 1:2 (metal:ligand) ratio. The structures of the polychelates have been assigned on the basis of their elemental analyses, IR and reflectance spectra and magnetic measurements. Thermal studies of polychelates have been carried out to determine their mode of decomposition, apparent activation energy and the order of each thermal reaction. Electrical conductivity behaviour of resin and its polychelates has also been studied.
