Reaction Conditions

Reaction Steps

ε-caprolactone (Cap), diethylene glycol (DEG), and stannous octoate were combined and melted under a nitrogen atmosphere. The mixture was charged into a nitrogen purged stirred reactor at 200° C. The contents were stirred at this temperature until maximum melt viscosity was achieved. Glycolide was melted under nitrogen and charged into the reactor. The temperature was increased to 225° C. over a 15 minute period, and the contents maintained at 225° C. until maximum melt viscosity was obtained. The polymer was discharged from the reactor, ground and dried in a vacuum oven for 12-18 hours at 100° C. and 0.2 mm Hg. Specific examples of polymers prepared by this procedure are summarized in Table 7.
