摘要
采用热分析方法研究抗氧剂种类及其添加量对聚乙二醇热稳定性的影响。结果指出，随着其添加量的增加，聚乙二醇的热分解起始温度和顶峰温度等增加；具有高阻碍酚基团含量且耐热的抗氧剂，对聚乙二醇的热氧化保护能力最强。
The effects of the kind of anti-oxident and its add-on on the thermal stability of polyglycol were studied by using DSC and TG in this paper.The results showed that the additivelevel of anti-oxident is increased.the start temperature and the top temperature of thermaldegradation of the polyglycol is increased.If the content of hindered phenol group in antioxident is higher and its thermal stability is better,then the anti-thermo-oxidative ability forthe polyglycol is stronger.
