Abstract:
Polylactic acid (PLA) is a biocompatible and biodegradable polymer, thus it is widely used in the medical area and is much more attractive. There are two main methods to synthetizing PLA, ring-opening polymerization of lactide and condensation polymerization of lactic acid. In this paper, the process of the new research of the PLA synthesis was reviewed. Beside, the PLA synthesis methods of reactive extrusion and direct melting polycondensation were introduced, which are two high efficiency methods. Finally, the foreground of PLA synthesis was prospected.
