摘要：

The catalysts with high activity and low toxicity for ring opening polymerization(ROP) of epsilon-caprolactone had drawn much attention both in academia and industry. A series of asymmetric Schiff base aluminum complexes containing ligands that differed in their steric properties were synthesized. Their catalytic properties in the solution polymerization of epsilon-CL were examined. The kinetics studies of all complexes/2-propanol indicated that all of polymerizations were first-ordered reaction to monomers, and the polymerization rate of electrophilic substituted complex was about 4 times the non-electrophilic substituted complex in ROP of epsilon-CL. The results evaluated that the electrophilic substituent of ligands ha great influence on the catalytic activity of the complex.
