Comparison of rheological frequency sweeps of chain extended hydrogels from various chemistries. (A) Thiol-maleimide with 1a; (B) thiol-maleimide with 1b; (C) thiol-dibromomaleimide; and (D) thiol-ene. The plateau modulus in the low frequency regime down to 0.001 rad/s is the entanglement plateau. The frequency spectrum shifts to the high-frequency end at elevated temperatures.
