Sheikh, A. Akhavan, F. Naimian, F. Khoylou, S. Hassanpour, M. Sohrabpour] To develop an environmentally degradable polymer material, a masterbatch pro-oxidant system was blended into low-density polyethylene. The polymer film samples were prepared by compression molding. The prepared films were placed under the natural environment of Tehran for weathering studies and accelerated conditions were also performed for UV aging in UV chamber. At different time intervals, the changes in chemical structure of photosensitized polyethylene samples were studied by FTIR and compared to that of the control polyethylene films. Also the mechanical properties of photosensitized polyethylene films were determined in comparison with the control films by measuring the tensile strength and elongation at break after exposure to the natural environment and UV radiation. Results showed that the overall rate of degradation process is clearly dependent on the polyethylene composition, test conditions (natural or accelerated), season of the year, and the duration of the weathering of the samples.
