| Abstract: | The kinetics of the oxygen-initiated polymerization of ethylene at high pressure up to 2,220 kbar was systematically investigated in a constant volume system in a temperature range from 60 to 250°C. In the higher temperature range (above 190°C), where no induction period exists, rate equations for both the oxygen consumption and the polymerization were derived by considering a retardation reaction by oxygen. The numerical calculation of these equations by the Runge-Kutta-Gil method indicated an excellent agreement with experimental results. |
