Samples were cooled down to -90 °C, held isothermally for 3 min, and then heated up to 120 °C. The heating/cooling rate was 5 °C/min. The data were analyzed using TRIOS software. In order to assess gel fraction of photocured elastomeric networks, samples were refluxed for 6 hours in a Soxhlet extraction apparatus (Behr Labor-Technik, Germany) in EtOAc. The samples were weighed before extraction (Winitial) and after drying (under reduced pressure until a constant mass was achieved) (Wfinal). The gel fraction was calculated according to Equation :
