Morphological, Photochemical and Spectroscopic Studies of Ibuprofen-Tin Complexes

Abstract

Poly(vinyl chloride) (PVC) was prepared and the photo-stabilization of polymer films was studied using ultraviolet (UV) light. The efficiency of the synthesized polymer complex of ibuprofen-tin which is the photo-stabilizer in this study afterward of 300 hours of irradiation were evaluated by calculate the constant of PVC degradation rate. The outcome of this research has shown that the additives (ibuprofen-tin complexes) effect significantly on the decreased degradation constant compare to blank PVC, without additives the rate of degradation constant of PVC is greater than when the additives are added. The surface morphologies of the irradiated polymer film with additives were researches utilizing Field Emission Scanning Electron Microscope (FESEM). It can be seen that the polymer film with added additives is less roughness than the irradiated PVC (blank). The organotin complexes behave in this study as a photostabilizer to maintain the PVC from any decomposition by absorbing the incident light and convert it over the time as a heat to the polymeric chain.
