- Abstract
This work reports on the preparation of highly pure cyclo-polylactides (Mn ≈ 4 000 g · mol-1) by the optimization of the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction applied on α-azide-ω-alkyne linear polylactide (PLA) precursors. By adjusting parameters such as the rate of reactant addition and the catalyst loading, monocyclic PLA's with a degree of purity of 93 % are obtained in few minutes. Highly pure monocycles (purity as high as 99.9 %) are also possibly prepared in few hours.
