It was shown that the physical filler-polymer and filler-filler interactions has a substantial role in controlling the vulcanization kinetics of solution-polymerized styrene-butadiene rubber (SSBR)/butadiene rubber filled with nano-silica in a sulfur vulcanization system. Kinetic studies by the oscillating disc rheometer revealed that the vulcanization rate suppressed as vinyl molecular microstructure of SSBR increases. A mechanism was proposed which correlates vulcanization kinetics of compounds to the dynamics of chains influenced by the SSBR molecular microstructure.
