摘　　要：综述了近年来国内外聚乳酸熔融聚合的研究情况,概述了直接熔融缩聚、熔融-固相和熔融-扩链合成聚乳酸的研究,并研究探讨了熔融聚合中影响聚乳酸相对分子质量的因素。The progress of the research recently on the polycondensation of poly （lactic acid）is reviewed at home and abroad. Which poly（lactie acid）syntheses is also investigated through the direct melt polycondensa tion,melt/solid polymerization as well as melt/chain-extending polymerization. And are discussed the factors that effect the molecular weight of the poly（lactic acid）in the melt polycondensation.
