- W1983893430 abstract "Radiation-induced oxidative degradation of stabilized polypropylene films using Co-60 γ irradiation at room temperature under different irradiation conditions (vacuum and oxygen) was investigated. Gas evolution, oxygen consumption, and mechanical properties were studied and analyzed quantitatively. It was found that the G values for the evolved gases during irradiation of stabilized polypropylene films under vacuum were G (H 2 ) = 2.5, G (CH 4 ) = 0.08, G (CO 2 ) = 0.02, and G (C 2 H 6 ) = 0.005. In the presence of oxygen, G (H 2 ) was the same, and the G values for other hydrocarbons were twice those under vacuum. The G values of oxidative products and oxygen consumption were G (CO) = 0.15, G (CO 2 ) = 0.5, and G (O 2 ) = 9.0 at oxygen pressure of 500 Torr and were dependent on oxygen pressure. The stabilized polypropylene, irradiated at low doses under different conditions (air, oxygen, and vacuum), shows mechanical properties almost similar to those of the unirradiated one. However, at higher doses the mechanical properties were sharply decreased and deterioration was enhanced in the presence of oxygen due to the oxidative degradation. On the other hand, post- irradiation effect on the stabilized polypropylene irradiated up to 0.02 MGy under vacuum, was studied at various annealing temperatures and different storage time at room temperature (25°C). Molecular weight distribution curves for polypropylene samples irradiated in air atmosphere show that degradation of the high molecular weight chains is the predominant process in the range of irradiation doses under investigation." @default.
