摘　　要：A series of anilido-imine zinc complexes ortho-C6H4（CH：NAr）（NAr）ZnEt[Ar=2,6-Me2C6H3（2a）; Ar=2,6-Et2C6H3（2b）] was synthesized, characterized and used as catalysts for the ring-opening polymerization of L-lactide in the presence of benzyl alcohol. The effects of the structures of catalysts and reaction conditions on the reactivity were investigated. The polymerization of L-lactide initiated by each of these complexes was found to take place with a controlled manner.A series of anilido-imine zinc complexes ortho-C6H4（CH：NAr）（NAr）ZnEt[Ar=2,6-Me2C6H3（2a）; Ar=2,6-Et2C6H3（2b）] was synthesized, characterized and used as catalysts for the ring-opening polymerization of L-lactide in the presence of benzyl alcohol.
