Reaction Conditions

Reaction Steps

l-Lactide (l-Lac, 153.3 grams) and Glycolide (Gly, 17.0 grams) were melted and charged into the reactor. The contents were stirred at 200° C. for 2 hours at which point the mixture had again obtained maximum melt viscosity. The polymer was discharged from the reactor, ground, and dried in a vacuum oven at 100° C. and 0.2 mm Hg. The polymer had in inherent viscosity of 1.40 dL/g in chloroform, measured at 30° C. on a 0.5% solution. The polymer composition, as measured by 1H-NMR spectroscopy was 15.9/74.1/10.0 weight percent CAP/l-LAC/Gly.
