Electrochemical Evidence of Transitory Ionic Species in the Vulcanization of Natural Rubber with Sulfur – 2-Mercaptobenzothiazole and Zinc Oxide

Continuous low level current (CLLC) measurements are used to investigate the vulcanization of natural rubber (NR) with sulfur (S), 2-mercaptobenzothiazole (MBT) and zinc oxide (ZnO) in the presence and absence of stearic acid (StAc). At elevated temperatures, the mixtures show increased conductivity attributable to the presence of ions. Current curve maxima characteristic of transitory ionic […] mehr...
