The effect of the mechanochemical treatment of components of the sulphurous vulcanizing group on the properties of rubber mixtures and rubbers on the basis of 1,4-cis-polyisopren, filled with carbon black N330, was investigated. The mechanochemical activation of the components was carried out by processing them in a device that is a reactor with magnetic elements and a coil of inductivity. When connecting the inductor to the electrical grid, the working elements are exposed to the magnetic field and began to move intensiocly way with the transfer of energy to powdered particles. The treatment of both individual components: zinc oxide, accelerators, and all components of the sulfur vulcanizing group leads to an increase in the rate and degree of structuring of rubber in the main vulcanization period and a decrease in the tendency of rubber to reverse in the postvulcanization stage. In this case the values of elasticity modules increase and mechanical losses in vulcanizates reduce as the temperature increases. Most of these changes in the properties of mixtures and rubbers are expressed in the processing of individual accelerators and together all components of the vulcanizing group. Storage of activated ingredients for 30 days does not lead to significant changes in the structure and properties of rubber mixtures and vulcanizates.
