The changes of the structural, spectroscopic, optical and thermal parameters of the samples are studied using different tools. FT-IR spectroscopy confirmed the complexation between the blends and Co+2-ions. The decrease or increase of IR band intensity with some shifts of other bands suggests an interaction and compatibility between PMMA/PVC blends with CoCl2 take place. The Ultra violet and visible (UV/Vis) spectra indicated that the presence of band gap energy depends on increasing of CoCl2 contents. The absorption intensity of the samples doped with CoCl2 becomes faint lower than the pure blend. The values of energy gap for direct and indirect transition decreases with the increase of CoCl2 due to the presence of charge transfer between PMMA/PVC and CoCl2. The thermogravimetric analysis (TGA) curves for all the samples have the same behavior and more steps of decomposition were observed. The reduction of mass loss for samples containing CoCl2 compared to the pure blend was observed and it was attributed to crosslink formation between the blend and CoCl2. (C) 2015 The Author.
