Abstract

Polypropylene/Montmorillonite nanocomposites were prepared by melt compounding with different concentrations of the compatibilizer, which is a maleic anhydride grafted polypropylene, using a reactive twin-screw extruder. They were characterized using tensile testing, DSC, XRD and TEM. It was found that beyond a certain concentration of the compatibilizer, the mechanical properties deteriorated. This was explained on the basis of shear rate-viscosity relationships and the nature of interfaces governing the nanocomposites.
