Abstract
The head to tail structure of normal PVC should be quite stable to UV radiation. However, the presence of polymer chains abnormalities in the responsible for the relative instability of PVC to light. Therefore, many attempts have been taken to investigate and elevate the photostability PVC. In this work, diphenylenehydramine compound had been used as a photostabilizer to PVC films with different concentrations and its efficiency was evaluated by weight loss percentage, carbonyl index methods after 60 hour of irradiation and surface morphology of PVC.
