ε-CAPROLACTONE p-DIOXANONE

Conditions

Workup

1. 1
   OtherThe copolymer was dried under vacuum (0.1 mm Hg) at 80° C. for about 80 hours
2. 2
   Otherto remove any unreacted monomer
3. 3
   Otherat 25° C
4. 4
   Otherat room temperature

Procedure

The procedure in Example 5A is substantially repeated except that 45.7 grams (0.40 mole) of ε-caprolactone and 61.3 grams (0.60 mole) of p-dioxanone were used. The copolymer was dried under vacuum (0.1 mm Hg) at 80° C. for about 80 hours to remove any unreacted monomer. The copolymer had an inherent viscosity of 0.18 dL/g in HFIP at 25° C. The copolymer was a liquid at room temperature. The molar ratio of PCL/PDS was found to be 46.7/53.3 by proton NMR.
