| Abstract: | Poly (L-lactide) was prepared by bulk polymerization ofL-lactide at 140°C in the presence of stannous octoate. The polymer products were characterized by number average molecular
weight Mn, weight average molecular weight Mw and molecular weight distribution MWD (M
w/M
n) respectively. The results showed that stannous octoate was a high effective catalyst, and coordinated insertion mechanism
of the reaction was proposed.
