Three kinds of particles of organically modified montmorillonite (OMT) intercalated with iron oxides (Fe‐OMT), hexadecyltrimethylammonium bromide (CTAB) and ethylamine (EA)‐modified zirconium phosphate (ZrP) intercalated with iron oxides, named as Fe‐ZrP(CTAB) and Fe‐ZrP(EA), respectively, were synthesized through a simple route. Characterization of these particles showed that they had a mesoporous lamellar structure with high specific surface area and mesoporous volume. The influence of these particles on the thermal properties and combustion effluents of polystyrene (PS) were comparatively studied with the widely used OMT. The results suggested that the presence of Fe‐OMT, Fe‐ZrP(CTAB), and Fe‐ZrP(EA) imparted PS with an increased thermal degradation onset temperature and a higher glass transition temperature, but they could not increase the thermo‐oxidative stability remarkably as OMT did. Meanwhile, Fe‐ZrP(CTAB) and Fe‐ZrP(EA) exhibited stronger acidity and higher efficiency in preventing the condensed phase oxidation than either OMT or Fe‐OMT, since they imparted the PS composites with a higher ratio of CO/CO2 in the combustion effluents. © 2015 Wiley Periodicals, Inc.
