| 英文摘要 | An achiral Schiff-base isopropoxide aluminum complex(II) was used for the stereoselective ring-opening polymerization of rac-lactide. The kinetics studies indicated that rac-lactide polymerization was first order kinetics to monomer concentration. There was linear relationship between the monomer conversion and molecular weights(M-n) of the polymer with a narrow molecular distribution. These phenomena indicated that the polymerization was well controllable. Moreover, the obtained poly( rac-lactide) was crystalline polymer with relative high t(m) (17 degrees C). C-13 NMR and homonuclear decoupled H-1 NMR spectra revealed that the polymerization of rac-lactide initiated by complex (II) resulted in the isotactic stereoblock polymer, which contained blocks with an average of 11 units of enantiomerically pure lactic acid. |
