Photoinduced ring-opening polymerizations

Photopolymerization is the subject of a growing interest both at industrial and academic levels because it provides high reaction kinetics, low emissions volatile organic solvents in some cases, shrinking stress. This polymerization route has been largely developed using radical vinyl monomers, but to lesser extent by ring-opening (ROP). Beyond epoxides, which were first monomers polymerized cationic (CROP), photopolymerization other cyclic recently spread out thanks emergence novel initiating systems. review states an overview spectrum that have light-induced processes. In part, photosensitive species able trigger or induce change kinetics ROP reactions are presented according their activation mechanism, i.e photouncaging, photoswitching photoredox. subsequent different monomer classes mechanisms described with emphasis on properties resulting materials. The last part covers use photoROP for several applications.
