Time‐lapse thiol‐acrylate polymerization using a pH clock reaction

Clocking the Clock: Programmable Acid Autocatalysis in the Chlorite‐Tetrathionate Reaction

“…This behavior is often due to autocatalysis, a positive feedback mechanism in which a reaction product catalyzes its own formation . Clock reactions are versatile tools for programming the assembly and/or disassembly of pH‐responsive building blocks, as well as for controlling polymerization and sol‐gel transition in the time domain.…”

What Is Nonlinear Dynamics and How Does It Relate to Polymers?

“…Hu et al [60] used the formaldehyde-bisulfite-sulfite clock reaction [61] (Figure 2.7) as a trigger for the polymerization of a trithiol with a triacrylate. (The addition of a thiol to an acrylate is base-catalyzed.)…”

Preparation and application of microparticles prepared via the primary amine‐catalyzed michael addition of a trithiol to a triacrylate

“…Chan et al has recently examined the major properties and kinetics of the primary amine‐catalyzed Michael reaction with various multifunctional thiols and acrylates 28. Hu et al used the formaldehyde‐sulfite clock reaction to trigger the time‐lapse Michael addition of a trithiol to a triacrylate 55…”
