Abstract A series of polypropylene (PP) nanocomposites containing 2, 4, and 6 wt % an organophilic montmorillonite clay was prepared via direct melt mixing in the presence maleic anhydride grafted (PP‐ g ‐MAH) as compatibilizing agent. Microstructure characterization performed by X‐ray diffraction analysis. Nanocomposites exhibited a 15 22% enhancement tensile modulus impact strength, respectively. The heat deflection temperature PP 36°C greater than for pure PP. Thermal mechanical properties were compared to traditional PP‐talc PP‐glass fiber composites. results showed that improved ordinary © 2009 Wiley Periodicals, Inc. J Appl Polym Sci,
