主　　题：Organometallic Poly(lactic acid) Ring-opening polymerization 

摘      要：The ring-opening polymerization of 5-methyl-1,3-dioxolane-2,4-dione（lactic O-carboxylic anhydride,LacOCA） using organometallic complexes,including Co（Ⅲ） complexes with Schiff base ligands,Tin（Ⅱ） alphatates and Al（Ⅲ） complexes with Schiff base ligands,was *** polymerization was carried out by treatment of the organometallic complexes with LacOCA in toluene under mild *** corresponding poly（lactic acid） was characterized by spectroscopy and thermal analyses,which revealed insight into the structure of the effective catalyst for the polymerization of LacOCA.
