Abstract
The effect of group IIB metal dithizone complexes on the properties of polystyrene have been investigated by GPC, FTIR, X-ray diffraction, TGA and DSC. The results of GPC and X-ray diffraction analysis proved that an improvement in the polymer chain ordered was achieved due to the presence of these complexes during the bulk polymerization of styrene monomer if compared with that of pure sample. TGA thermograms showed that the thermal stability of polystyrene is enhanced with increasing complex concentration. However, mercury gives the best results followed by cadmium and zinc dithizonate. DSC scans for the different polymer samples provides a further support to the TGA data.
