研究高分子化合物热稳定性最基本的方法是差热分析和热失重分析。聚苯硫醚的差热分析和热失重分析结果,最早见之于R.W.Lenz等的工作。以后,G.F.L.Ehlers等及R.M.Black等都作过报导。他们所用的样品或是利用Macallum法或是利用硫酚盐法制得的。至于美国菲力浦公司利用硫化钠和对二氯苯在N-甲基吡咯烷酮溶剂中经缩聚而制得的聚苯硫醚,我们只看到它在惰性气氛中的热失重曲线。 The most basic method to study the thermal stability of polymer compounds is differential thermal analysis and thermogravimetric analysis. Differential thermal analysis of polyphenylene sulfide and thermogravimetric analysis of the results found in the work of R.W.Lenz et al. Later, G.F.L.Ehlers et al. And R. M. Black et al. Have reported. The samples they used were made either by the Macallum method or by the thiophenol method. As for the Phillips Company in the United States, which uses polyphenylene sulfide prepared by polycondensation of sodium sulfide and p-dichlorobenzene in N-methylpyrrolidone solvent, we only see its TG curve in an inert atmosphere.
