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
