摘要： 在“双碳”政策的大背景下，热固性高分子材料的降解回收是当今高分子科学领域热点话题之一。开展可解聚的热固性高分子材料制备的综合实验非常符合当今社会发展，有利于促进学生对一线科研的了解。本实验利用迈克尔(Michael)加成反应制备可解聚的热固性高分子材料。迈克尔加成反应生成的β-氨基酯结构可在酸性条件下解离，从而使得所制备的热固性聚合物可以快速地解聚合。通过本实验的实践，学生可以掌握当前制备可解聚热固性高分子材料的最新方法，了解当前高分子材料的发展方向。本综合实验将先进的科研成果与一线课堂教学结合，为学生的创新能力和综合运用专业知识能力的培养奠定基础。

Abstract: The degradation and recycling of thermosetting polymers have emerged as a hot-topic in the field of polymer science under the background of “dual carbon” policy. Conducting a comprehensive experiment on the preparation of depolymerizable thermosetting polymers aligns well with modern societal development and facilitates students’ understanding of frontline scientific research. This experiment employs the Michael addition reaction to synthesize depolymerizable thermosetting polymers. The β-amino ester groups formed through the Michael addition reaction can dissociate under acidic conditions, enabling rapid depolymerization of the prepared thermosets. By engaging in this experiment, students can master the latest methods for fabricating depolymerizable thermosetting polymers and gain insight into the current trends in polymer materials research. This comprehensive experiment integrates cutting-edge scientific achievements with classroom teaching, providing a solid foundation for cultivating students’ innovation capabilities and their ability to apply professional knowledge comprehensively.
