Description
Summary:This work introduces the oscillation rheometry as a method for determination of processing stability of polymers, which are high sensitive to degradation during melt processing. The oscillation rheometry was found as a simple and rapid method which could indicate the first stages of degradation process. Changes in relative complex viscosity were taken as indicator of processing stability. It was shown that changes in relative complex viscosity reflect changes in molecular weight of degraded polymer very well.
