Polymerization of ε-Caprolactone Catalyzed by the Divalent Sm Complex of Schiff Base Ligand [2-OC6H4CH=N(2,6-iPr2C6H3)]2Sm(THF)2
Abstract:
The divalent Sm complex supported by Schiff base ligand [2-OC6H4CH=N(2,6-iPr2C6H3)]2Sm(THF)2 has been prepared by the reaction of [2-OC6H4CH=N(2,6-iPr2C6H3)]2Na with SmI2 in THF. It exhibits a good catalytic activity for the polymerization of X-caprolactone, and the polymer obtained has a narrow molecular weight distribution.
