“…Almost all polymerization reactions were conducted in organic solvents, such as: toluene [40], 1,4-dioxane [41], isopropyl ether [42], isooctane [43], diphenyl ether [44], cyclohexane [45]. The reaction was also carried out in supercritical carbon dioxide [46,47], ionic liquids [48][49][50], and recently, in aqueous dispersion [51]. The best solvent for eROP with CALB seems to be toluene [52].…”
