Comparison of storage moduli (G′) of HMWH-Polymer hydrogels under different conditions. These experiments were conducted with 10 wt% hydrogels comprising HMWH (f = 8) and a molar ratio of maleimide/thiol = 1.7 /1. The polymer component was varied as given below. (a) HMWH-PEG (average Mn 10,000 g/mol) and HMWH-PEG (average Mn 4,600 g/mol), 25 °C; (b) HMWH-PEG (average Mn 10,000 g/mol) and HMWH-Pluronic F127, 25 °C; (c) HMWH-Pluronic F127 at 25 °C and 37 °C. The relatively large error in this particular set of measurements likely arises from a small amount of dimerization between PEG polymer end groups, as assessed via 1H NMR, during the elapsed time between the two sets of measurements.
