Cure kinetics and swelling behaviour in polybutadiene rubber
Two polybutadiene rubbers (BR) with different 1,4-cis content were used to prepare compounds with a cure system based on sulfur and TBBS (N-t-butyl-2-benzothiazole sulfenamide). Torque curves, measured with a moving die rheometer at a temperature of 433 K, were used to characterize the vulcanization...
