摘要

高分子化学是高分子材料相关专业本科学生的一门基础专业课程。将科研成果作为延伸的阅读资料，有利于帮助本科生巩固知识的同时激发他们的科学探究精神，培养他们的创新能力，同时为探讨科研反哺教学提供新的参考。本文将科研成果“1

1-二苯基-2-三硝基苯肼(DPPH)应用于验证芳腈基树脂自由基聚合机制”融入自由基阻聚/缓聚章节的教学，作为课后的延伸阅读资料，有机结合“课前-课后”的教学模式，帮助学生强化基础知识，也启发了学生运用基础知识解决科研问题的思路。

Abstract

Polymer chemistry is the primary course for undergraduate students majoring in polymer science. Combing scientific research achievements as extended reading materials is beneficial for undergraduate students to consolidate their knowledge

stimulate their scientific exploration spirit

cultivate their innovation ability

and provide new references for exploring the optimistic interaction between teaching and scientific research. This article integrates the scientific research achievement “1

1-diphenyl-2-trinitrophenylhydrazine (DPPH) applied to verify the free radical polymerization mechanism of aromatic nitrile resin” into the teaching of the free radical inhibition/retardation chapter. As an extended reading material after class

it effectively combines the “pre class-post class” teaching mode to help students strengthen basic knowledge and inspire students to use basic knowledge to solve scientific research issues.
