The dynamic thermomechanical tests were performed using a DMA/SDTA 1+ instrument from Mettler Toledo (Greifensee, Switzerland). Measurements were made in single cantilever mode on 30 mm × 4 mm × 2 mm specimens cut from the gauge length of tensile test specimens. First, a series of pre-tests (strain sweep measurements) were performed, to determine the linear viscoelastic region of the specimens tested. The actual viscoelastic measurements were performed in the temperature range of -80-120 °C at a heating rate of 3 °C/min, with a constant displacement amplitude of 20 µm and a frequency of 1 Hz. Finally, frequency sweep tests from 0.1 to 100 Hz were performed in the linear viscoelastic region for the same displacement amplitude at room temperature (25 ºC).
