The thiol-Michael reaction is a highly efficient reaction with applications ranging from protein modification to polymer crosslinking. Although known for over 50 years, the thiol-Michael reaction has seen a significant resurgence in recent years due to its “click” like nature. However, despite the highly efficient nature of the thiol-Michael reaction upon appropriate external stimulus such as high temperature or high pH, the thiol-Michael reaction can be activated and made dynamic. In this abstract, thiol-Michael adducts are introduced into polymer materials as crosslinkers. Initially, the dynamic exchange properties of the thiol-Michael adducts are explored in solution phase model systems, to evaluate the kinetics of dynamic exchange. Subsequently the mechanical properties of dynamic thiol-Michael materials are evaluated.
