| titleOfInvention | A Method for Manufacturing Poly(2-Hydroxyalkanoic Acid), and the Poly(2-Hydroxyalkanoic Acid) Obtainable Thereby |
| abstract | A method for manufacturing poly(2-hydroxyalkanoic acid), preferably a poly(lactic acid), is disclosed. The method comprises the steps of: mixing a cyclic diester of a 2-hydroxyalkanoic acid and a polymerization catalyst, polymerizing the cyclic diester to form poly(2-hydroxyalkanoic acid) in liquid phase, adding a peroxide-based compound as a catalyst deactivating agent to the liquid phase, applying a devolatilisation step to the liquid phase, and allowing the poly(2-hydroxyalkanoic acid) to solidify, characterized in that an end-capping agent is added to the poly(2-hydroxyalkanoic acid) in the liquid phase. The present invention also relates to a poly(2-hydroxyalkanoic acid), preferably a poly(lactic acid), obtainable with said method characterized in that the polymer has a Mn abs ranging between 10000 and 250000 g/mol, preferably between 20000 and 85000 g/mol. |
