摘要

超支化聚硅氧烷作为一种新型的超支化聚合物

兼具了超支化聚合物和硅氧聚合物的优点

是《高分子化学》课程教学中具有典型代表性的前沿教学案例。本文以超支化聚硅氧烷为案例教学对象

从单体选择、原料配比、聚合过程控制等方面进行讨论

重点讲授逐步聚合、缩聚反应、凝胶点的预测等相关知识点;在此基础上进一步延伸到高分子材料结构与性能的关系及新型超支化聚合物制备方法上。通过课程设计

组织学生将线上预习、传统讲授、课堂讨论及线下学习进行良好结合

激发学生学习兴趣及主观能动性

并对教学效果和教学质量进行了讨论探索。

Abstract

Hyperbranched polysiloxane is a new type of hyperbranched polymer

which has the advantages of hyperbranched polymer and siloxane

thus it is a typical case in the teaching of polymer chemistry. This paper takes hyperbranched polysiloxane as the teaching object

discusses monomer selection

raw material ratio

polymerization process control and other aspects

and focuses on gradual polymerization

polycondensation reaction

gel point prediction and other related knowledge points. On this basis

the relationship between the structure and properties of polymers and the preparation method of novel hyperbranched polymers are extended. Through course design

students are organized to study this course by combining online preview

traditional teaching

classroom discussion and offline learning. Furthermore

the students' learning interest and subjective initiative are stimulated. The teaching effect and teaching quality are also discussed and explored.
