For this, we concentrated on samples crosslinked with 10 and 15 wt.% polyperoxides. For the samples crosslinked with 10 wt.% several interesting observations were apparent. For the hydrogels crosslinked for the shortest period (10 min) and at the lowest temperature (120 °C) the EWC at room temperature reached 96.17 ± 0.15 % while these samples completely dissolved when incubated at 35 °C (Figure ). When crosslinked at higher temperature (140 -160 °C), the resulting hydrogels show better stability. Interestingly, when we increasing the incubation temperature further to 60 °C, all samples crosslinked at ≤160 °C dissolved completely (Figure ). At 15 wt. % of crosslinker, this picture does not change much. Hydrogels obtained at 120 -140 °C and relatively short crosslinking time dissolved at higher temperature, while samples crosslinked at 180 and 200 °C give stable hydrogels.
