Natural rubber (NR)‐montmorillonite (MMT) nanocomposites with different organomodified MMT contents prepared by in situ organomodified and latex compounding method, followed by melt compounding technique are reported in this work. The morphology as well as the static and dynamic mechanical properties of the nanocomposites, are investigated. By means of SAXS and FESEM analysis, MMT is found to have partly intercalated and exfoliated structure in NR matrix. The modulus, tensile strength, and storage modulus at low strain of NR‐MMT are enhanced compared to unfilled NR but hysteresis loss tended to increase with raising organomodified MMT content. The overall results showed that the presence of 5 phr of organomodified MMT filled NR gave the best balance between mechanical and dynamical properties.
