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环合制。

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.

结果表明在含羟化合物的丙交酯/合体系中,羟化合物作为共引发剂参与了丙交酯的开环合。

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.

丙交酯是由乳酸制乳酸的中间体,其产率偏低是制约乳酸大规模应用的关键。
