摘要

“共聚合”是高分子化学教学中的重点章节之一。本文从研究“共聚合”的意义出发

详细论述了二元共聚物组成微分方程的推导、竞聚率的引入和共聚行为类型辨析三个部分在“共聚合”教学过程中的作用

阐述了对“共聚合”教学主线的认识。以丙烯腈-丁二烯-苯乙烯共聚物(ABS)的实际生产过程为例

提出以提问式教学法引导学生明晰学习内容

围绕如何合成组成均一的共聚物这一核心内容由浅及深的设置问题

加深学生对知识点的理解、融合及应用

体现“两性一度”在“共聚合”教学中的实践。

Abstract

"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" .
