摘　　要：从《高分子物理》考试试题实例出发,抓住聚合物材料的"结构决定性能,并最终决定用途"这条主线,详述了链结构因素(主链和取代基)和分子间作用力对聚合物玻璃化转变温度(Tg)的影响,并结合不同高分子材料的用途进行分析,使学生真切了解到材料结构与性能及用途之间的关系。这种理论联系实际的案例教学法有利于加深学生对高分子材料的感性认识,引发学生学习的广泛兴趣,促使教师进行自我教育和提高业务水平,从而取得良好的教学效果。Properties of polymer materials are determined by their structures, and finally affect their applications. Catching this primary point and combining applications of different polymer materials, effects of chain structure （including main chain and substitute group） on glass transition temperatures are detailedly discussed from the test question in the examination of Polymer Physics. Relationship between structure and property is deeply comprehended by the students. The case teaching method makes the students＇ perceptual knowledge of polymer materials and learning interests to be improved. Furthermore,the teachers＇ self-education and professional skills are promoted. And then the teaching effect will be much better than the normal method.
