The free radical polymerization process is a very important chapter in the course of "

Polymer Preparation Engineering

"

mainly involving bulk polymerization

emulsion polymerization

suspension polymerization and solution polymerization. The selection and utilization of initiators will greatly affect the effect of these four kinds of polymerization. It is important to control the free radical polymerization by correctly understanding the kinds

characteristics

kinetics processes and the selection rules of different initiators in different polymerization reactions. However

due to a wide variety of initiators and different characteristics

students often deviate from understanding and memory

resulting in polymerization failure in the actual production. This paper will use the grid teaching method to help students build up the memory grid of initiator. The complexity of the content is presented to students through grid curriculum design. And the complex dynamics formula is decomposed into simple and understandable basic variables to the students. The students will overcome the fear of difficulty in the learning process. We can promote subjective initiative of students who are the main characters in the class.
