PLA PEG

Syntheses and properties of PLA-PEG block copolymers were introduced, and their applications for micelles, microspheres and nanoparticles in drug delivery system were also reviewed.

介绍PLA - PEG嵌段共聚物的合成和性质，综述其作为胶束、微球、纳米粒等的载体在药物释放系统中的应用。

Recently, poly (d, l-lactide) -poly (ethylene glycol) (PLA-PEG) block copolymers have been widely applied owing to the favorable biodegradability and biocompatibility.

聚乳酸-聚乙二醇嵌段共聚物因具备良好的生物可降解性和相容性而得到广泛应用。

The results indicated that the addition of PEG has little effect on the molecular structure of PLA filament whose mechanical property has been improved, especially the elongation at break.

结果表明：PEG的加入对PLA纤维分子结构的影响不明显，但却明显改善了PLA纤维的力学性能，特别是断裂伸长率有明显的提高。
