Abstract: A methodology for producing modified nanoclays which, when added to an elastomer, provide elastomeric nanocomposites with improved ageing, rheological and mechanical properties, and which can be devoid of, or containing low amount of, a filler such as carbon black, is provided. The modified nanoclays are made of a nanoclay, such as an organomodified nanoclay, modified so as to be in association with an amine-containing antioxidant and optionally also with a silyl-containing compound, such as mercaptosiloxane. Also provided are processes of preparing the modified nanoclays, elastomeric composites containing same and articles containing the elastomeric composites.
