摘要：

介绍一个绿色高分子化学综合实验。在水相中，苯乙炔通过有机铑配合物催化聚合得到聚苯乙炔，利用红外光谱仪、核磁共振仪、紫外-可见分光光度计、荧光光谱仪和热重分析仪对其结构和光热性能进行研究。本实验难度适中，可以通过溶剂为可变因素展开分析讨论，引导学生主动思考。实验内容涵盖高分子化学、应用波谱学和聚合物仪器分析与表征等知识点。本实验的实施不仅可提升学生的综合运用专业知识能力，还可培养学生系统的科研思维和环保意识。

Abstract:

This study introduced a comprehensive experiment of green polymer chemistry. Phenylacetylene was polymerized by using organic rhodium complex as the catalyst in the aqueous solution. The molecular structure and photothermal properties of phenylacetylene (PPA) were characterized by fouriter transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), ultraviolet-visible spectrophotometer (UV-Vis), fluorescence spectrometer and thermogravimetric analyzer. Furthermore, this designed experiment is easy to operate and can use the solvent as a variable factor to inspire students to think actively. The experimental content covers the knowledge points of polymer chemistry, applied spectroscopy and polymer instrumental analysis and characterization. The implementation of this experiment can not only improve the students' comprehensive ability to use professional knowledge, but also cultivate the students' systematic scientific research thinking and environmental protection awareness.
