| Abstract: | The polymerization condition of lactide is studied in this paper. The thermal behavior of PLA are characterized by DSC and TGA. Mechanical properties of PLA films with various copolymerization ratios are compared. Degradability of PLA is determined in buffer solutions and a microbial ecological environment respectively. By means of changing polymerization condition as well as copolymerization ratio of L-Lactide to DL-Lactide, the properties of PLA can be adjusted for different needs. |

| Keywords: | Polylactic acid polymerization condition copolymerization ratio mechanical property degradability |
