| Abstract: | This article researched the mechanism of synthesis of poly(lactic acid) with direct condensation polymerization Catalyzed by SO~(2-)_4/TiO_2-Ce~(4 ),The experimental result indicated that:the mechanism of synthesis of polylactides with direct condensation polymerization catalyzed by SO~(2-)_4/TiO_2-Ce~(4 )is acidic polymerization,The acidity of catalyst stronger will synthesizes the higher molecular weight Polylactides. |
