Hiroshi Watanabe: Do you see any effect related to the long equilibration time of the samples? How reversible are the results when going back to room temperature?
Answer: All samples were equilibrated for about an hour in the rheometer at a temperature of 130 °C, and normal forces were checked to be relaxed before any measurement. Measurements were conducted from high to low and then, from low to high temperatures, in order to check the reversibility of the measurements. At each temperature, a 30 min time sweep test was performed at 1 rad/s to equilibrate the sample, and each frequency sweep test was repeated to double-check the reproducibility of the experiment. In all cases, the experiments were reversible for both the viscoelastic data and the small angle x-ray scattering (SAXS) data, with fast equilibration time.
