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.

这些结果表明在含物的交酯/醇铁体系中,物作为共引发剂参与了交酯的开环。

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.

交酯是由乳酸制备乳酸的中间体,其产率偏低是制约乳酸大规模应用的关键。
