✦ Synopsis

Abstract

The synthesis of a rapidly forming redox responsive poly(ferrocenylsilane)‐poly(ethylene glycol) (PFS‐PEG)‐based hydrogel is described, achieved by a thiol‐Michael addition click reaction. PFS bearing acrylate side groups (PFS‐acryl) was synthesized by side group modification of poly(ferrocenyl(3‐iodopropyl)methylsilane) (PFS‐I) and characterized by ^1^H NMR, ^13^C NMR, and FT‐IR spectroscopy. The equilibrium swelling ratio, morphology, rheology, and redox responsive properties of the PFS‐PEG‐based hydrogel are reported. magnified image

## Abstract An acryloyl end-capped four-arm star-shaped poly(ethylene glycol)-branched-oligo(l-lactide) (4A-PEG-PLA) macromer was firstly prepared. A novel kind of hydrogels was synthesized via the Michael-type addition reaction between (2S,3S)-1,4-bis-sulfanylbutane-2,3-diol (dithiothreitol) and t
