聚乳酸研究和产业发展情况及面临的主要问题探讨

Research and Industry Development Situation of Polylactic Acid and Main Problems Discussion

聚乳酸是一种具有良好生物相容性、在环境中可降解的高分子材料,可取代石油基不能降解的塑料制品,广泛应用于各个领域,受到越来越多的关注。本文主要介绍的是以有机胍为催化剂,采用丙交酯开环聚合法生产聚乳酸的工艺。并对聚乳酸的改性研究、发展前景及急需解决的主要问题作了简要论述和讨论。

Polylactic acid, a biodegradable materials are widely used in various fields, which has good bio- compatibility, and get more and more attention. Organic guanidine as catalyst, using the process of laetide ringopening polymerization of poly lactic acid （PLA） production. Modification research, development prospect of polylactic acid and main problems need to be solved are briefly discussed.
