Analysis of network structure formed in styrene-butadiene rubber cured with sulfur/TBBS system

Several styrene-butadiene rubber (SBR) compounds were prepared with different cure systems based on sulfur and TBBS (N-i-butyl-2-benzothiazole sulfenamide), varying the amount of sulfur and accelerator between 0.5 and 2.5 phr in the formulation. Torque curves, measured with a moving die rheometer at...
