Abstract In the present investigation, polypropylene clay nanocomposites (PP‐CNs) are prepared by melt compounding using the Polymer NanoComposite Injection Molding Compounder (PNC‐IMC) with different nanoclays and at varying compatibilizer/nanoclay ratios. A specially devised hyperbolical nozzle is used to induce elongational flow for better mechanical properties. Statistical analysis of the mechanical properties reveal that PP‐CNs based on mica‐phlogopite is superior to other PP‐CNs. Beside intercalated and exfoliated structures the SAXS results confirms that the PP‐CNs show well aligned and also randomly disordered structures. TGA shows among the investigated nanoclays organic modified montmorillonite (OMMT) shows substantial improvement in thermal stability of PP‐CNs.
