Procedure

Polymerisation was performed as in Example 3, but the amounts of ingredients were following: 85.2 g of L-lactic acid (78 mole-%), 25.9 g of itaconic acid (16.5 mole-%), 1.4 g of pentaerythritol (0.8 mole-%), 25 g of betulin (4.7 mole-%) and 0.0375 g of tin(II)octoate. Total polymerisation time was 20 hours. As product, was obtained hard brittle brownish yellow mass, which was end-functionalised according to the example 11 and finally crosslinked by radicals.
