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.
