β-form polylactide( β-PLA) has been a hot topic in modification- PLA because of its excellent impact,heat resistance and other special properties. This paper reviewed the developments in β- PLA in recent years. It simply described the structure and some characterization techniques of β-form of PLLA and SC-PLA,and summarized the influence of processing conditions,annealing and nucleating agents on the β-PLLA. Furthermore,the formation of β-form of PLLA / PDLA stereocomplex was discussed. Trends in research of the β-form of PLA were also presented.
