Synthesis and characterization of poly (D, L-lactide) by ring-opening polymerization

Polylactides (PLA) have become very important biomedical materials due to the combination of their bioresorbable,biocompatible, biodegradable and mechanical properties.They have been widely used in drug controllable release, surgical suture, orthopedics bone internal fixation and tissueengineering [1]. An effective method for the synthesis ofpolylactides is the ring-opening polymerization (ROP) of lactides [2]. This paper reports the details of the methods of synthesis and discusses some properties of polylactide
