In this study dynamically vulcanized nanocomposites based on (polypropylene (PP)/styrene butadiene rubber (SBR)/organoclay) were prepared through using different sequence of feeding in melt mixing method. The effect of organically modified nanoclay and mixing procedure on the structure of nanocomposites was investigated. X-ray diffraction analysis (XRD) revealed different dispersion statuses resulted from different feeding methods. Moreover, the morphology of the prepared nanocomposites was characterized by scanning electron microscopy (SEM) and correlated with feeding sequence
