Itaconic acid → HCID 86617348, compound

Participants

Reaction Steps

Polymerisation was performed in the same principle as in Example 9, but the betulin was added to the reaction mixture in three portions during first two hours. The amounts of the ingredients were following: 85.2 g of L-lactic acid (89 mole-%), 7.4 g of itaconic acid (5.5 mole-%), 25 g of betulin (5.5 mole-%) and 0.0375 g of tin(II)octoate. Total polymerisation time was 14 hours. The product was hard, brittle, shiny, orange mass, which was water resistant. Synthesis product was observed to crosslink with end-functionalisation (Example 11) by radicals.
