生物医用材料聚乳酸的合成及其催化体系研究进展

Research Progress on Synthesis and Catalytic System of Biomedical PLA

介绍了近十年来国内外聚乳酸合成方法及值化体系的研究进展。对倦化体系按照金属．非金属等进行了归纳分类。对所使用值化剂开环聚合丙交殛的性能进行了比较与讨论，着重介绍了新型绿色值化荆的研究进展，并展望了合成聚乳酸研究的发展方向及应用前景。

The synthesis methods and catalytic systems on polylactic acid （PLA） reported at domestic and foreign in the past ten years were introduced. According to the classification of metal, non- metal and other catalytic systems, the performances of ring-opening polymerization lactide with the catalyst used by the researchers were compared and discussed. The research progress of new green catalysts was introduced emphatically. The development directions of polylactic acid synthesis were prospected.
