    Mathematical characterization of the values of rheologic variables during the networking reaction of rubber mixtures based on SBR

  • Original language description

    The article presents an analysis of crossbridging reaction using measurements of time dependencies of torque at constant temperature from the range 100 up to 200 ° C. The measured results obtained on sample based on styrene - butadiene (SBS) prepared inthe laboratory show the behaviour which can be well decsribed by equations of chemical reactions of first-order kinetics. It is possible mathematically describe significant constants of the kinetics of networking reaction (induction period, reaction ratecoefficient) by the solution of differential equations and by mathematical aproximation. Constants are exponentially dependent on the temperature of vulcanization, while dependencies are Arrhenius like. Math description allows describe the progress of the vulcanization reaction also in the temperature range outside of the monitoring interval, i.e. in the area of extremely long times required for the realization of the crossbridging reaction.
