The aim of this work was to study the activity of novel benzalkonium and ammonium ionic liquids with 2-mercaptobenzothiazolate as accelerators in the sulfur vulcanization of butadiene-styrene elastomer (SBR). In this Article, the effect of the ionic liquids on the vulcanization kinetics of the rubber compounds, the cross link density, and the mechanical properties of the vulcanizates, as well as their resistance to thermal and UV aging, was studied. The application of novel ionic liquids allowed for the elimination of N-cyclohexyl-2-benzothiazolesulfenamide from SBR compounds and for the considerable reduction of the amount of 2-mercaptobenzothiazole present in rubber products. Synthesized salts seem to be good substitutes for standard accelerators in the sulfur vulcanization of SBR rubber, without the observation of any detrimental effects on the vulcanization process, the physical properties, or the thermal stability of the obtained vulcanizates.
