On the basis of results of measurements of physical properties and solvent swelling of the extrudates, it has been observed that epoxidized natural rubber (ENR) interacts chemically with intermediate super abrasion furnace (ISAF) carbon black when the mix of the two was extruded at 130–160°C in a Monsanto Processability Tester (MPT). The extent of interaction between the rubber and filler depends on the following factors: extrusion time, carbon black loading, shear rate, and the extent of oxidation on the carbon black surface. Addition of the silane coupling agent, namely, N ‐3‐(‐ N ‐vinyl benzyl amino) ethyl‐γ‐amino propyl trimethoxy silane monohydrochloride, enhances the rate of the interaction. © 1999 John Wiley & Sons, Inc.
