Cationic photopolymerization is amongst the greenest processes used to obtain polymers since light is abundant, inexpensive and allows for rapid and waste-less curing at room temperature. Moreover, in the current search for the reduction of the environmental impacts of polymers, the use of biobased monomers is one of the most crucial stakes. At the crossroads of these domains, biobased monomers photopolymerization offers the best of both. Hence, this review aims at underlying the increasing importance of cationic photopolymerization in combination with bio-based photopolymerizable monomers, and describes the numerous reactive species derived from bioresources that can lead to innovative materials through cationic photopolymerization reactions. This review intends to be a guide to orientate academic teams and industries involved in reducing both environmental impacts and toxicity towards the synthesis of environmentally safe materials. The recent advances on the photochemical systems used, the toxicity of the cationic photoinitiating systems, the reactivity of the new epoxy bio-sourced monomers, their thermomechanical properties as well as the applications of the targeted materials will be described.

阳离子光聚合是用于获得聚合物的最环保的方法之一，因为光充足、价格低廉并且可以在室温下快速且无浪费地固化。此外，在当前寻求减少聚合物对环境影响的过程中，生物基单体的使用是最关键的风险之一。在这些领域的十字路口，生物基单体光聚合提供了两者的最佳选择。因此，本综述旨在说明阳离子光聚合与生物基光聚合单体的重要性日益增加，并描述了源自生物资源的众多活性物质，这些物质可通过阳离子光聚合反应产生创新材料。本综述旨在指导学术团队和行业参与减少环境影响和毒性，以合成对环境安全的材料。将介绍所用光化学体系的最新进展、阳离子光引发体系的毒性、新型环氧生物源单体的反应性、它们的热机械性能以及目标材料的应用。
