| Abstract: | Inherent flame retardant styrenic copolymer/organic modified montmorillonite(OMMT) nanocomposites[P(St-co-AEPPA)/OMMT] were prepared by in situ bulk copolymerization. Ordinary polystyrene/organic modified montmorillonite nanocomposites(PS/OMMT) were prepared as comparative experiments. Effect of phosphorus-nitrogen containing monomer(AEPPA) and OMMT on styrenic copolymer was studied. The structure and morphology of nanocomposites were characterized by X-ray diffraction(XRD) and transmission electron microscopy(TEM), and the dispersion mechanism of OMMT in matrix was discussed. Differential scanning calorimetry(DSC), thermogravimetric analysis(TGA) and microscale combustion calorimeter(MCC) were used to research the thermal properties and flammability of composites. The results showed that the incorporation of AEPPA monomer and OMMT could significantly improve the thermal stability and flame retardancy of matrix. |
