520			_aNatural rubber (NR) compounds were prepared with in situ precipitated silica in the presence of epoxidised natural rubber (ENR) as a coupling agent. In situ silica masterbatches were prepared from NR latex along with ENR. For this, NR latex was mixed with a suitable amount of ENR latex and precipitation of silica was carried out using sodium silicate and ammonium chloride. Compounds were prepared with these masterbatches. The mechanical properties of the vulcanisates were compared with two reference compounds prepared from NR and commercially available silica with and without a silane-coupling agent Si-69@. The NR-silica composites prepared with ENR as the coupling agent showed better mechanical properties and improved rubber-filler interaction.
