High molecular weight PLA can be prepared by ring-opening polymerization of lactides.

高分子量的聚交酯主交酯开环聚制备。

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.

这些结果表明在含羟化的交酯/醇铁聚体系中,羟化为共引发剂参与了交酯的开环聚。

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.

交酯是乳酸制备聚乳酸的中间体,其产率偏低是制约聚乳酸大规模应用的关键。
