| 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. |
