Polypropylene (PP)/montmorillonite (MMT) nanocomposites have been prepared by melt intercalation using organomontmorillonite and conventional twin screw extrusion. The dispersibility of silicate layers of the montmorillonite in the composites was investigated by using X‐ray diffractometer and transmission electron microscopy (TEM). The silicate layers of montmorillonite are dispersed at the nanometer level in the PP matrix, as revealed by X‐ray and TEM results. The tensile strength of PP/MMT is not much improved compared with pure PP or conventional filled composites. However, the impact strength is greatly improved at lower content of MMT. © 2000 Society of Chemical Industry
