Temperature dependence of melt viscosity of polymers

  • V. E. Dobrescu
  • C. Radovici


The temperature dependence of steady-state melt viscosity of several polymers — semicrystalline and amorphous — in a broad temperature range has been studied. In many cases this dependence can not be expressed by an Arrhenius type equation. Breaks and slope changes have been observed. The influence of polymer morphology and molecular weight and the influence of pressure are presented.
