Abstract: A comprehensive chemistry experiment is recommended. In this experiment, the pretreatment, controllable catalytic degradation, analytical characterization of thermosetting unsaturated polyester resin and gel swelling were mainly included. The students could not only gain the knowledge on the waste plastic pollution, but also get the basic principles and methods of controllable catalysis and gel preparation. The experiment enables students to experience the theory applying to practice and making waste profitable, which helps to enhance students’ interest in chemical experiments and cultivate their comprehensive innovation ability.

Key words: Waste thermosetting unsaturated polyester resin, Catalytic degradation, Hydrogels, Experimental design
