The ring-opening polymerization mechanism of lactide in the presence of hydroxyl compounds was studied by using ferric ethoxide and ferric n-butoxide as catalysts respectively.

这些结果表明在含化物的丙交酯/醇铁聚体系,化物引发剂参与了丙交酯的开环聚。

Lactide is the midbody for the preparation of poly(lactic acid), the ratio of lactic acid to lactide is low and hamper the extensive application of PLA.

丙交酯是由乳酸制备聚乳酸的间体,其产率偏低是制约聚乳酸大规模应用的关键。
