摘要
The divalent Sm complex supported by Schiff base ligand [2 OC 6H 4CH [ZJLX,Y] N(2,6 i Pr 2 C 6H 3)] 2Sm(THF) 2 has been prepared by the reaction of 2Sm(THF) 2 has been prepared by the reaction of [2 OC 6H 4CH [ZJLX,Y] N(2,6 i Pr 2C 6H 3)]Na Na with SmI 2 in THF. It exhibits a good catalytic activity for the polymerization of ε caprolactone, and the polymer obtained has a narrow molecular weight distribution.
