실험 절차

The polymerisation was performed like in Example 1, but the amount of the ingredients were 846.3 g aqueous L-lactic acid (86 mole-%), 66.2 g itaconic acid (6 mole-%), 67.4 g ε-caprolactone (6 mole-%), 20.1 g pentaerythritol (2 mole-%) and 0.39 g tin(II) octoate, and the polymerisation time was 26 hours.
