Enhanced aminolysis of cyclic carbonates by β-hydroxyamines for fully biobased polyhydroxyurethanes Baptiste Quiennea, Rinaldo Polib,*, Julien Pinauda, Sylvain Caillola,* aICGM, Univ Montpellier, CNRS, ENSCM, Montpellier, France bCNRS, LCC (Laboratoire de Chimie de Coordination), Université de Toulouse, UPS, INPT, 205 Route de Narbonne, BP 44099, F-31077, Toulouse Cedex 4, France Abstract The aminolysis of five-membered cyclic carbonates which results in polyhydroxyurethanes (PHUs) is one of the most promising synthetic pathway to achieve isocyanate-free polyurethanes (NIPUs), one of the main industrial challenges over the coming years. This study highlighted the higher reactivity of β-hydroxyamines toward cyclic carbonate in comparison to classical alkylamines through the determination of their reaction rate constants.
