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.

丙由乳酸制备聚乳酸的中间体,其产率偏低制约聚乳酸规模应用的关键。

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丙/聚合体系中,羟基化合物作为共引发剂参与了丙的开环聚合。
