“…Polyethers are a type of polymeric materials with tunable properties, which have been widely used as intermediates in the manufacture of polyurethane, antifouling coating material, electrolytes, and in cosmetic and pharmaceutical products . Metal-catalyzed ring-opening polymerization (ROP) of epoxides is a most efficient method for preparing polyethers . To date, a series of metal complexes, including Al, Zn, Mn, Co, Cr, group IV, Fe, and rare-earth complexes, have been reported to be efficient initiators for the ROP of epoxides.…”
