The viscosity of the polymers was determined via melt rheology at temperatures between 180 and 150 °C. Flow sweeps were measured with a constant frequency of 10 rad*s -1 and increasing shear rate from 1 to 100 s -1 . Preliminary experiments ensured that all measurements were done within the linear viscoelastic region (LVE). To better compare the different samples over the whole temperature range, the viscosity value at 10 s -1 was plotted against the temperature, as the viscosity value remained constant over the whole shear rate range. This enables a quick comparison of the viscosity at different temperatures and different polymer samples.
