In this paper, we report on the thermal degradation behaviours and combustion attributes of some polymers based on polystyrene (PSt). Here, both additive and reactive strategies were employed, through the bulk polymerization route, where the modifying groups incorporated P-atom in various chemical environments. These included oxidation states of III or V, and the loading of phosphorus was kept at ca. 2 wt.% in all cases. The characterization techniques that were employed for the recovered products included spectroscopic, thermal, and calorimetric. It was found that the presence of different modifying groups influenced the degradation characteristics of the base polymer, and also exerted varying degrees of combustion inhibition. In all cases, the modification of the base matrix resulted in a noticeable degree of fire retardance as compared to that of the virgin material. Therefore, some of the modifications presented have the potential to be explored on a commercial scale.
在本文中，我们报告了一些基于聚苯乙烯（PSt）的聚合物的热降解行为和燃烧特性。在此，通过本体聚合路线采用了添加和反应两种策略，其中改性基团在各种化学环境中引入了P原子。这些包括III或V的氧化态，并且在所有情况下磷的负载量保持在约2 wt.%。用于回收产物的表征技术包括光谱、热分析和量热分析。发现不同改性基团的存在影响了基础聚合物的降解特性，并且还表现出不同程度的燃烧抑制作用。在所有情况下，与原始材料相比，基础基体的改性导致了显著程度的阻燃性。因此，所提出的一些改性方法具有在商业规模上进行探索的潜力。
