摘要

聚乳酸作为石油基塑料的绿色替代品具有十分广阔的市场前景。简要介绍了聚乳酸市场现状，并从生物合成和生物-化学合成两个途径对目前研究较多的聚乳酸合成技术进行了综述，最后提出高效绿色催化剂以及快速合成技术的开发是聚乳酸合成工艺研究中的重点。

Abstract

As a green alternative to petroleum-based plastics,polylactic acid (PLA) has very broad market prospect.Present situation of PLA market is briefly introduced.PLA synthesis technologies that are commonly studied are reviewed from bio-synthesis and bio-chemical synthesis aspects.The development of efficient green catalysts as well as rapid-synthesis technology are the emphasis and difficulty in the study of PLA synthesis technology.
