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

高分子量的丙交酯主要由丙交酯开制备。

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物的丙交酯/醇铁,羟化物作为共引发剂参与了丙交酯的开。

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乳酸的间,其产率偏低是制约乳酸大规模应用的关键。
