The disperson of sulphur in rubber compounds was studied using radioisotopes. The radioactivity of the 13S isotope introduced into rubber compounds was measured by volumetric and surface methods. These methods could be used to investigate physical and chemical processes in rubber and to optimise technical conditions of tyre production. It was found that the radioisotopic methods could be used in studies of sulphur blooming. Experimental data were obtained on the effect of mixing and the storage temps. of the rubber compound on these processes. Rubber compounds containing soluble sulphur, insoluble Crystex sulphur and T-accelarator were used for the studies.
