influence of molecular microstructure of solution-polymerized styrene-butadiene rubber types on vulcanization kinetics

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.
