摘　　要：介绍了聚乳酸的性质和应用;总结了丙交酯开环聚合和乳酸直接缩聚这2种制备聚乳酸的方法;展望了聚乳酸及其共聚物的发展前景,并指出了在其研究与开发中所存在的问题.The properties and application of polylactide are reviewed. Two synthetic methods which comprise ringopening polymerization of lactide and direct polycondensation of lactic acid are introduced. Moreover, the direction of the development of polylactide and copolylactide is projected. Finally, the problems existing in the research and exploration of polylactide are pointed out.
