    Abstract: The invention relates to a silane/filler preparation, consisting essentially of from 5 to 70% by weight of at least one silane corresponding to the following formula Xp-CmH2m+1-pSiRn1(OR)3-n, I in which X=a halogen atom, preferably chlorine or bromine, p=1 or 2, m=1 to 5, R1=a C1-C5 alkyl group, C5-C8-cycloalkyl group or a phenyl group, R=a C1-C5-alkyl group, a C5-C8-cycloalkyl group, a phenyl group, a benzyl group or a C1-C5-alkoxy-C1-C5-alkyl group, and n=0, 1 or 2, and-respectively balanced to 100%-from 95 to 30% by weight of at lesat one inorganic filler, preferably carbon black and silicate fillers as, e.g., silica. There is also disclosed a process for the production of the silane/filler preparation and its use in optionally cross-linkable polymeric moulding compositions or vulcanizable or cross-linkable rubber moulding compositions such as sulphur-vulcanizable moulding compositions based on natural rubber and/or synthetic rubber.

    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.
