An innovative organoclay containing polybutadiene chains was prepared in order to make rubber nanocomposites based on natural rubber or styrene–butadiene copolymer. It was obtained by reacting a maleinised polybutadiene oligomer with the CH2CH2OH moieties present in the ammonium cation of a commercially available organoclay (Cloisite 30B). Elastomeric nanocomposites were also prepared with a reference organoclay, formed by intercalation during mixing with dialkyl dimethylammonium chloride. Sulphur cured nanocomposites were characterised in terms of curing kinetics, morphology, tensile and dynamic-mechanical properties; chemical interactions between the modifier of the new organoclay and the matrices can be inferred by experimental evidences.
