“…Thermally initiated ionic and coordination ROP as well as controlled ROP have been recently reviewed and detailed in [ 3 ]. Cationic polymerization (CP) reactions (of e.g., divinylethers) and the particular cationic ROP of cyclic monomers (e.g., epoxides, oxiranes such as cyclohexene oxide) can also be initiated by light (see, e.g., in books [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ] and in review papers [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]).…”
