N2 - The properties of immiscible blends of PTT and PP were modified by grafting and nanoparticle inclusion. The observed synergistic effect of MWCNTs and MA-g-PP on the thermal and viscoelastic properties of PTT/PP blends was studied in detail and the properties of the composites were compared with those of ungrafted PP. The variation in the surface morphology of the blends and composites due to the added MA-g-PP was examined using microscopic techniques such as scanning electron microscopy and high-resolution transmission electron microscopy. The SEM and TEM micrographs established the distinction in morphology due to the synergism of grafting and MWCNTs. Thermal and physico-mechanical properties of the compatibilized and uncompatibilized blends and composites were analyzed using different thermal analytical techniques and tensile studies. Tensile measurements showed a substantial enhancement in the tensile properties through the compatibilization process and this can be correlated to the enhanced dispersion of MWCNTs and interfacial adhesion between components. The DMA and rheological studies supported the concept of synergism caused by MA-g-PP and MWCNTs. Improved viscoelastic properties suggest improved interfacial adhesion between the components due to the synergistic effect of MA-g-PP and MWCNTs.
