Progress in stereoselective polymerization of poly (lactic acid)

From the view of the synthesis of poly(lactic acid) with high optical activity,the progress in the recent synthesis of poly(lactic acid) through stereoselective and non-stereoselective polymerization at home and aboard is summarized and reviewed.The prospect of stereoselective polymerization of poly(lactic acid) is also forecasted,the key to promote the development of poly(lactic acid) industry should be the selection of catalytic system with high stereoselectivity and the optimization of polymerization processes.
