Steps involved in thiol-ene polymerization reaction (i) Initiation: Generation of thiyl radicals (*) via irradiation of thiol functionalized photoinitiator; (ii) Propagation: Thiyl radicals react with unreacted electron-rich or strained -enes monomers/polymers yielding polymers with end-group radicals along with intermolecular thioether bonds and (iii) Termination: May terminate by disulfide bond formation via thiyl-thiyl radical coupling.
