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