摘要

摘要控制从反应器中释放出来的气流中氧气和二氧化碳的浓度，并在其中对样品进行加热，可用于研究聚合物材料的热稳定性。这种方法被称为氧化热图法（oxithermography），包括分析实验数据（氧化热图），即气流中氧气浓度下降和二氧化碳出现随温度条件变化而变化的情况。这种方法可以监测聚合物成分中引入的填料对其热稳定性的影响。以纯聚丙烯和添加二氧化钛的聚丙烯为例，展示了氧化热成像仪在研究氧化热稳定性方面的应用。

Oxythermography for Exploring the Thermal Stability of Polymer Materials: A Novel Analytical Approach

Abstract

The control of oxygen and carbon dioxide concentrations in an airflow released from a reactor, in which a sample is heated, can be used to investigate the thermal stability of polymer materials. This approach, known as oxithermography, involves analyzing experimental data (oxithermograms), representing the variation in oxygen concentration decrease and carbon dioxide appearance in an airflow with changing temperature conditions. This method allows for monitoring the effect of fillers introduced into polymer compositions on their thermal stability. The application of oxithermography to studying oxidative thermostability is demonstrated using pure polypropylene and polypropylene with titanium dioxide admixtures as examples.
