Work is focused on measuring of processing stability by the oscillation rheometry. It is a method for description of processing stability of high sensitively polymers, which degrade during melt processing. The oscillation rheometry is a rapid method which could indicate the process of degradation during thermomechanical stress . The decrease of complex viscosity indicates degradation of polymers during the testing of sample. It has been shown that decrease of relative complex viscosity reflects changes in molecular weight of degraded polymers.
