The effect of different modes of filler addition on dynamic mechanical properties of 50/50 blends of epoxidized natural rubber (ENR) and cis‐1,4‐polybutadiene rubber (BR) has been studied. The present study is confined to the systems that have fillers alone to reduce complexities due to the presence of other compounding ingredients and vulcanization. The effects of both carbon black and silica filler have been investigated. The mode of filler addition was found to have a profound influence on the loss tangent (tan δ) peak height, its spread, and the storage modulus, E′ value. The tendency of the filler to adhere predominantly to one of the phases depends on the mode of filler addition and the processing history rather than the individual component polarity or viscosity.
