Методика

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.
