The effect of montmorillonite (Mt) and the treated montmorillonite (MtT) with sulfuric acid on the efficiency of nanoparticles of ammonium polyphosphate (APP) has been studied. Five samples containing different percentage of montmorillonite are prepared and other five samples containing treated montmorillonite also prepared. The chemical analysis (XRF), the spectroscopic measurements (XRD and IR) and the morphology (SEM) studied have been performed to identify the sulfuric acid treatment for the montmorillonite on the chemical composition and on the structure of the montmorillonite layers. The results have been revealed that the acid treatment changes the layered structure of montmorillonite and no effects on the chemical composition. The thermogravimetric analysis (TGA) is used to evaluate the ammonium polyphosphate (APP)/ montmorillonite (Mt) or APP/ montmorillonite treatment (MtT) as flame retardants for Polypropylene (PP). The results show that both treated and untreated montmorillonite when mixed with APP accelerate the first step of the thermal degradation. Also, it is indicated that the time of degradation increased by adding treated or untreated montmorillonite to APP in the following sequence PP

蒙脱石的改性及其对PP/APP热稳定性的影响
研究了蒙脱石（Mt）和经硫酸处理的蒙脱石（MtT）对聚磷酸铵（APP）纳米粒子效率的影响。制备了五个含有不同百分比蒙脱石的样品，并且还制备了其他五个含有处理过的蒙脱石的样品。已经进行了化学分析 (XRF)、光谱测量 (XRD 和 IR) 和形态学 (SEM) 研究，以确定蒙脱石的硫酸处理对化学成分和蒙脱石层结构的影响。结果表明，酸处理改变了蒙脱石的层状结构，对化学成分没有影响。热重分析 (TGA) 用于评估聚磷酸铵 (APP)/蒙脱石 (Mt) 或 APP/蒙脱石处理 (MtT) 作为聚丙烯 (PP) 的阻燃剂。结果表明，经处理和未经处理的蒙脱土与 APP 混合时均加速了热降解的第一步。此外，还表明，通过按以下顺序 PP 向 APP 中添加处理过或未处理过的蒙脱石，降解时间增加
