FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing particles of powder for production of a rubber composition. Method includes pulverisation of the particles of the compound described by formula (I), with median diameter (50 % D) more than 100 microns using a spray device in presence of at least one component selected from a group consisting of silicon dioxide, talc and clay, to produce particles of the compound described by formula (I), with median diameter (50 % D) 100 mcm or less.
EFFECT: invention simplifies the technology of production of particles for use in curative rubber mixtures.
