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.
