Radioisotope methods have been analyzed to study the dispersion of sulfur in rubber compounds. The radioactivity of the 35S isotope introduced into rubber compounds has been measured by volumetric and surface methods. These methods can be applied to investigate physical and chemical processes in rub

โฆ Synopsis
It was found that radioisotopic methods can be adapted for analysis of ZnO dispersion in rubber compounds. This method is characterized by a sensitivity of g ZnO/l g rubber compound. This fact enables application of this method in technological and research problems.
