Abstract The curative interactions with the participation of dicyclohexylbenzothiazole‐2‐sulfenamide (DCBS), stearic acid (SA), ZnO, S, and Co(II) stearate (octadecanoate‐CoC 18 ) as adhesive promoter have been investigated by means of DSC calorimetry, EPR, and IR spectroscopy in the absence of rubber. It has been found that in the presence of CoC 18 , DCBS, and S, structural changes have been observed on the action of heat, which are connected with the formation of polysulfide complexes between Co 2+ ions, DCBS fragments, and sulphur. In the presence of SA and ZnO in the five‐component system, zinc(II) octadecanoate is formed. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 81: 2936–2943, 2001
