Polystyrene combined with fire retardants and nanomaterials have been used to study the thermal stability and fire properties. The nanomaterials used are a montmorillonite clay and carbon nanotubes. The amounts of fire retardants and nanomaterials were varied in order to study the effect of their loading on the properties. The samples were prepared by melt blending and analyzed by thermogravimetric analysis and cone calorimetry. In this study, representatives ofthree classes of fire retardants were used: bromine, decabromodiphenyl oxide; phosphorus, resorcinol diphosphate; and minerals, alumina trihydrate.
