摘要(Abstract)：
研究了以乳酸为单体,用直接缩聚法合成聚乳酸的反应过程。利用联苯醚作为溶剂,与体系的水分进行共沸回流,达到充分脱水的目的。探讨了反应历程中包括温度、反应时间、溶剂用量、催化剂用量等参数对聚合产物的分子量的影响。
Polylactic acid is produced directly from lactic acid. Diphenyl ether is used as solvent and azeotropied with water.The affecting factors in the progress on molecular weight,such as temperature,time,amount of solvent and catalyst,etc.are studied.
