Reaction Steps
Glycolide (0.21 moles) was mixed with ε-caprolactone (4.0 moles) and a catalytic amount of stannous octoate (0.8 mmole) and glycolic acid (0.40 moles). The system was heated to 150° C. and was stirred at this temperature for 14 hours. At the conclusion of the reaction, the unreacted monomer was removed by heating at 120° C. under reduced pressure for 1 hour. The resulting polymer had a peak melting temperature of 54.3° C. as measured by DSC.
