英文摘要	a series of bimetallic schiff-base ligands were synthesized and used to prepare aluminum complexes. all the complexes were characterized by h-1, c-13 nmr and elemental analysis. these complexes were used as catalysts in the rac-lactide and epsilon-caprolactone polymerization. isotactic enriched polylactides were obtained by using these complexes. all polymerizations were living with the narrow molar mass distributions. the m-n(obsd) of the isolated polymers was in good agreement with m-n(calcd). kinetic studies showed that the polymerizations were first-ordered with respect to both lactide and caprolactone monomers. the more bulky substituents with more steric hindrance of the complexes had relatively poor activity. the increasing temperature had a positive effect as the polymerization rate increased with increasing temperature.
