Polystyrene‐calcium phosphate nanocomposites were prepared in an internal mixer by the melt mixing technique with as synthesized calcium phosphate nanoparticles. The composites were characterized by different techniques. Rheological aspects of the composites revealed the ease of processability and viscosity characteristics of the composites. Thermogravimetric analysis of the composites showed that the thermal stability of the composites improved by the incorporation of the nanofillers especially for the 3% and 5% filled systems. Flammability tests were carried out with a microcalorimeter, and it was found that the heat release rate decreased with respect to the filler loading.
