摘　　要：高分子物理作为高分子专业的核心课程,着重研究高分子独特的物理性能。高分子链结构的教学内容阐明了高分子化学结构与物理性能间关系,是理解高分子材料宏观性能的基础。塑料作为一大类重要的高分子材料,其种类繁多、品类复杂,同种塑料不同牌号间也存在性能差异。高分子物理作为前序课程,其教学内容对塑料材料的讲解有重要的指导性作用,本文以“高分子链结构”为例,阐述了分子链键接序列结构、分子量及其分布、链拓扑构筑等特征的差异对塑料物理性质、加工性质的影响,使用商品化塑料产品作为实例提升教学效果。在授课过程中,引导学生建立不同课程间教学内容的联系,构建高分子学科教学内容的连贯性。在教学中,培养学生构建系统的高分子学科知识体系,对学生学习和掌握高分子学科知识有重要意义。Polymer physics,as a core course in the field of polymer science,focuses on the unique physical properties of polymers.The teaching content related to polymer chain structures explains the relationship between the chemical structure and physical properties of polymers,forming the foundation for understanding the macroscopic properties of polymer materials.Plastics,as a major category of important polymer materials,are diverse and complex,with performance differences even among different grades of the same type of plastic.As a precursor course,the teaching content of polymer physics plays a crucial guiding role in the study of plastic materials.This paper uses“polymer chain structure”as an example to explain how variations in the sequence structure of molecular chains,molecular weight and its distribution,and chain topology affect the physical and processing properties of plastics.The use of commercial plastic products as examples enhances the effectiveness of teaching.Students are encouraged to establish connections between the content of different courses,thus building continuity in the teaching content of polymer science.It is of great significance to cultivate students’ability to construct a systematic knowledge framework in polymer science for their learning and mastery of the subject.
