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

高分子量的交酯主要由交酯开环合。

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.

交酯是由乳酸乳酸的中间体,其产是约乳酸大规模应用的关键。

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基化合物的交酯/醇铁合体系中,羟基化合物作为共引发剂参与了交酯的开环合。
