PLA

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

高分子量的聚丙要由丙开环聚合制。

2.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.

丙是由乳酸制聚乳酸的中间体,其产率偏低是制约聚乳酸大用的关键。
