Abstract A direct polymerization process was developed to synthesize homo- and copolymers of L-lactic acid. The properties and structures of the products were characterized by 1H nuclear magnetic resonance (1H-NMR). It was found that PLLA can be prepared by direct synthesis using melt polycondensation. Moreover, the number-average molecular weight and compositions of each polymer was determined by 1H-NMR spectra. In the meantime, the 1H-NMR spectra was also used for racemization analysis.
