To measure dynamic mechanical analysis (DMA) of bulk cured samples using the heated mold, cuboid samples (DIN EN ISO 6721) were cured as described previously, and sanded to correct any geometric irregularities. Measurements were performed in torsional mode in a temperature range of -50 to 200 °C with a heating rate of 2 °C min -1 , a shear strain of 0.1% and a frequency of 1 Hz.
