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 (\overline{Mn}) and compositions of each polymer was determined
by ¹H-NMR spectra. In the meantime, the ¹H-NMR spectra was also used for racemization analysis..},
