Disintegration times (tc) of hydrogels prepared from 4-armPEG-amide-DBCO with varying ratios of 4-armPEG-ester-N3 and 4-armPEG-N3 (r) predicted by the theoretical model and validated by experimental data. (A,B) Prediction curves of the intact linkage fraction P vs time in PBS (pH 7.4) and α-MEM, respectively. The red dotted line represents the critical intact linkage fraction of the network (Pc = 1/3), and its crosspoint with each curve indicates the predicted tc for the specific formulation. (C,D) Predicted (blue) and experimentally observed (red) tc in PBS (pH 7.4) and α-MEM, respectively.
