Abstract: The invention relates to the organic silanpolysulphane mixture of the general formula (RO)3 Si (CH2)xS-Sz-S(CH2)xSi (ОR)3 (I) where R – linear or branched C1-8 alkyl, in particular C1-3 alkyl X – the whole number 1-8 z – the whole number 0-6; the total organic silanpolysulphane with z=0 or z=1 representing at least 80 mass % in the mixture providing that the fraction with z=0 is below 80% while the fraction with z equal 2 through 6 does not exceed 20%. The invention relates also to the rubber compositions on the basis of these mixtures in particular for the tracks of the tire protectors.
