A B S T R A C T The invention relates to a process for the production of thiuram polysulfides substituted by aliphatic, araliphatic and/or cycloaliphatic hydrocarbon radicals. In this process, correspondingly substituted secondary amines are reacted with carbon disulfide and sulfur in a solvent at 0 to 150°C in the presence of a tertiary amine, a metal-containing catalyst and oxygen or an oxygen-containing gas. By virtue of its high purity, the product obtained by this process may be used directly, i.e. without preliminary purification, for its intended purpose, for example as a vulcanization accelerator or sulfur donor. This process is distinguished from other known processes for the production of thiuram polysulfides in particular by the substantially quantitative yields and selectivities and by its high economy which derives above all from the fact that the reaction is carried out in a single stage without expensive auxiliaries and from the elimination of a purification step.
