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

高分子量聚丙交酯主要由丙交酯聚合制备。

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.

这表明在含羟基化合物丙交酯/醇铁聚合体中,羟基化合物作为共引发剂参与了丙交酯聚合。

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中间体,其产率偏低是制约聚乳酸大规模应用关键。
