1.High molecular weight PLA can be prepared by ring-opening polymerization of lactides.
高分子量的丙交主要由丙交开环合制备。
2.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丙交/醇铁合体中,羟基化合物作为共引发剂参与了丙交的开环合。
3.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.
