摘要：

Investigations and numerical representation of chemical transformation mechanisms occurring during polymer processing have recently become a very important problem. In this paper a model put forward to describe the interrelation of mechanical degradation and thermal oxidation phenomena during PE extrusion. This model permits determination of changes in molecular weight, the amounts of reacted oxygen and the quantities of accumulated peroxide together with the amount of the inhibitor used during extrusion. These parameters have a significant affect on the physical and mechanical properties of the polymer and make it possible to assess its lifetime in finished products under operating conditions.
