“…Two different dimensionless values of U A = 10 and 20 were chosen (cf. Figure ) according to the data in refs . The uptake velocity of the collector screen was kept at 10 m/min, and the initial Deborah number at the die exit De 0 = 400, which corresponds to the relaxation time of the molten polymer of 0.1 s; the polymer density was taken as 0.99 g/cm 3 .…”

“…This activation energy of flow is the energy needed to overcome the internal flow resistance and to achieve motion of the individual molecules. 57 The construction of a mastercurve by shifting individual frequency sweeps is displayed in Fig ( S3). From these shift factors (aT), plots of ln(aT) in function of (1/T) were constructed (Fig.…”
