Recently, Lewis pairs composed of organobases and organoboranes have shown high catalytic activity for the synthesis of polyethers by ring-opening polymerization of epoxides. Surprisingly, copolymerization of cyclic anhydride and a large excess of epoxide we conducted at elevated temperatures were f...
