摘要
聚乳酸是一种化学合成的新型降解塑料,它能完全生物降解生成CO_2和H_2O。聚乳酸的生产方法有丙交酯法和直接聚合法。介绍了聚乳酸的物理力学性能、用途、生物分解特性,以及国外的产业动态。研究和生产聚乳酸,对于解决“白色污染”具有积极意义。
Polylacetic acid(PLA) used by two-step methods of lactide and direct polymerization is a new-type synthesizingplastics and can be biologically degradated into carbon dioxide and water. The physical and mechanical properties, application, biologically degradating characterization of PLA and its abroad industrial developments are introduced. There is an active significance to research and produce PLA for resolving white pollution.
