"copolymerization" is one of the priority chapters in polymer chemistry teaching. Beginning from the study of the significance of "copolymerization"

this paper discusses in detail the function of the derivation of the differential equation of the composition of binary copolymer

the introduction of the reactivity rate and the discrimination of the type of copolymerization behavior in the teaching process of "copolymerization"

and expounds the understanding of the main line of teaching and learning of "copolymerization" . And taking the actual production process of acrylonitrile-butadiene-styrene copolymer (ABS) as an example

this paper proposes the question-asking teaching method to guide students to clarify the learning content

sets the problem from shallow to deep focusing on the core content of how to synthesize homogeneous copolymers

deepens the students' understanding

integration and application of the knowledge points and embodies the practice of high gradation

innovativeness and challenges in the teaching of "copolymerization" .
