“…This third thermal event was the one considered to determine the T d of the hydrogels, 373.9 and 369.8 • C, respectively, since it is the event that reflects the decomposition of the hydrogel structure and the effect of crosslinking on the final material. These T d s are higher than the T d for this type of HPG, around 300 • C [50], as a result of the crosslinking, which leads to an increase in the thermal stability of polymers [56,57].…”

“…This pendant group is present in the hydrogel structures when some OA molecules connect to it through the reaction of only one of their two carboxylic groups. The absorption at 1000-1150 cm −1 is related to C-O stretching of the ether groups present in the polyglycerol backbone [50,51] and all samples present this band with similar intensities. The results, therefore, are evidence of the crosslinking of the HPG with OA through ester bonds to form the hydrogels and that HPG-OA2 presents a higher crosslinking degree when compared to HPG-OA1, which is in accordance with their %gel results and The results, therefore, are evidence of the crosslinking of the HPG with OA through ester bonds to form the hydrogels and that HPG-OA2 presents a higher crosslinking degree when compared to HPG-OA1, which is in accordance with their %gel results and characteristic firmness.…”
