Abstract: This invention relates to mixtures of organosilanepolysulphanes of the general formula (RO)3Si(CH2)x S-Sz - S (CH2)x Si(OR)3 (I) in which: R means alkyl, linear or branched, having 1-8 C atoms, in particular 1-3 C atoms; x is an integer from 1-8; z is 0 to 6; wherein the sum of the proportions of polysulphanes in which z = 0 and z = 1 amounts to ~ 80% (by weight), providing that the proportion of compounds in which z = 0 remains below 80%, and the proportion of organosilanepolysulphanes in which z is an integer from 2 to 6 does not exceed a proportion of 20 wt.% in the mixtures, and to rubber compounds produced using these mixtures, in particular for tyre treads. The invention also provides processes for the production of such rubber compounds.
