Reaction Steps
The procedure described in Example 1 is substantially reproduced by reacting 91.3 gm (0.8 mole) of ε-caprolactone with 139.3 gm (1.2 mole) of glycolide. A weight loss of 1.1% is observed upon devolatilization. The I.V. of the copolymer is 1.83 dl/g in HFIP and the mole ratio of PCL/PGA is found to be 38.7/61.3 by NMR.
