| Summary, etc. | A strategy was attempted to produce high-molecular-weight poly(L-lactic acid)(PLLA)through the direct condensation polymerization of L-lactic acid in bulk state. Polymerizations were carried out with titanium(IV)butoxide (TNBT)as a catalyst employing different duration of decompression, esterification and polycondensation. The molecular weights were characterized by using the gel permeation chromatography (GPC). The stereosequences were analyzed from the 13C NMR spectra on the basis of the triad fractions. |
