摘　　要：结晶聚合物涉及大量复杂的概念和理论知识,是高分子物理教学的重难点内容之一。其中“系带分子”作为结晶聚合物中的重要组成部分,不仅仅是联结晶体与晶体的系带,也是理解结晶聚合物结构与性能的“系带”。本文提出以结晶聚合物中的“系带分子”为线索,对结晶聚合物涉及的相关知识进行串连和梳理,阐述聚合物的晶体结构模型以及结晶聚合物结构与性能的关系,帮助学生理解和记忆结晶聚合物相关知识的同时,建立对结晶高分子结构与性能对应关系的理解,进而形成在学习高分子相关知识时从结构到性能的思维逻辑。同时也通过鼓励学生自主查阅文献,学习和总结学术上关于结晶聚合物研究的历史沿革和最新进展的形式,进一步加深学生对课堂知识的掌握,锻炼学生们独立思考的能力。The teaching of crystalline polymers is one of the most important parts in the syllabus of polymer physics,including massive concepts and theories of polymer crystallization.Tie molecules,as the essential part of crystalline polymers,are not only the link of polymer crystallites,but also the key which helps to understand the structure and property of crystalline polymers.In this work,the crystal models of polymers and the structure-property relationship of crystalline polymers are elaborated,focusing on the effects associated with the tie molecules.In this way,it is much easier for students to understand the structures as well as the corresponding properties of crystalline polymers.Reading literature and recapitulating the recent advances in the field of crystalline polymers are also encouraged to improve the students’ability of independent thinking.
