    Abstract: Low-dusting, readily-dispersible granules (I) based on precipitated silicate fillers (II) modified with organosilicon compounds of formula ÄR n(R-(CH2)iO)3-nSi-(CH2)y-(CH2)zÜqB (III), in which B = -SCN, -SH, -Cl, -NH2 (if q = 1) or -Sx- (if q = 2); R = H or 1-4C alkyl; R = 1-4C alkyl; n = 0, 1 or 2; y = 0-19; z, i = 1; x = 2-8; and in which the degree of reaction of the alkoxy groups is expressed as the ratio of integrated C-NMR signals as follows: when R is not H, (CH2)i/(CH2)z = not more than 0.4 for q = 2 or not more than 0.15 for q = 1; when R = H, ÄR-(CH2)iÜ/(CH2)z = not more than 0.4 for q = 2 or not more than 0.15 for q = 1. Also claimed is (i) a process for the production of (I), and (ii) vulcanised rubber mixtures containing (I).

    Abstract: The invention is directed to the modification of synthetic, silicatic fillers with water insoluble sulfur containing organosilicon compounds. For this purpose, the fillers are converted into an aqueous suspension and treated with the organosilicon compounds, optionally in the presence of an emulsifier. The thus modified filler in vulcanized rubber mixtures results in a clear improvement in the industrial properties of the rubber.
