The development of more sustainable and eco-friendly polymers has attracted much attention from researchers over the past decades. Among the different strategies that can be implemented towards this goal, the substitution of the toxic reagents/monomers often used in polyurethane chemistry has stimulated much innovation leading to the development of the hydroxylated version of PURs, namely, the poly(hydroxyurethane)s (PHURs). However, some PHURs remain far from being sustainable as their synthesis may involve monomers and/or solvents displaying poor environmental impacts. Herein, we report on the use of more sustainable conditions to synthesize the biobased polycarbonates involved in the aminolysis reaction. In addition, we demonstrate that the use of renewable deep eutectic solvents (DESs) can act both as excellent solvents and organocatalysts to promote the aminolysis reaction.
在过去几十年中，开发更可持续和环保的聚合物引起了研究人员的极大关注。在实现这一目标的不同策略中，替代聚氨酯化学中常用的有毒试剂/单体激发了许多创新，从而开发出了 PUR 的羟化版本，即聚（羟基urethane）（PHUR）。然而，一些 PHUR 仍然远非可持续的，因为它们的合成可能涉及到单体和/或溶剂，这些单体和/或溶剂对环境的影响较差。在此，我们报告了在更可持续的条件下合成参与氨解反应的生物基聚碳酸酯的使用情况。此外，我们还证明了可再生深共熔溶剂（DES）可同时作为优异的溶剂和有机催化剂来促进氨解反应。
