Epoxidised natural rubber as a coupling agent in in situ precipitated silica-natural rubber composites

Natural 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 precipita...
