ACS化学学士学位指南要求课程包括聚合物化学原理和不同类别大分子的合成。有机化学可以为高分子化学原理提供重要的介绍,光化学诱导自由基聚合是一种生成聚合物的方法,非常适合在本课程中进行探索。介绍了在本科有机化学实验室中开展的一个通过光聚合反应合成交联聚合物来探索光化学和自由基化学的实验。一个探究式的设计是用来介绍聚合反应,学生了解空气敏感的实验室技术。学生必须汇集他们的数据来解释分子结构如何影响宏观材料的物理性质。
The ACS Guidelines for bachelor’s degrees in chemistry call for the curriculum to include polymer chemistry principles and the synthesis of different classes of macromolecules. Organic chemistry can provide an important introduction to polymer chemistry principles, and photochemically induced radical polymerization is one method for generating polymers that is well suited to be explored in this course. The development and implementation of an experiment for undergraduate organic chemistry laboratory in which students explore both photochemistry and radical chemistry by synthesizing cross-linked polymers via photopolymerization is reported. An inquiry design is used to introduce polymerization reactions, and students learn about air-sensitive lab techniques. Students must pool their data to explain how molecular structure affects the physical properties of a macroscopic material.
