反応手順
ε-Caprolactone (170 g, 1.49 mole), glycolide (30 g, 0.26 mole), lauryl alcohol (1.37 g, 7.3×10-3 mole) and stannous octoate (0.052 g, 1.2×10-4 mole) were combined in a stirred reactor under nitrogen at 180° C. The mixture was stirred at 180° C. for 4.5 hours. The resulting polymer had an inherent viscosity of 0.68 dl/g (0.5 g/dl in CHCl3). The composition was determined by 1H NMR to be 85 wt. % ε-caprilactone and 15 wt. % glycolide.
