Abstract
Silica surfaces are contacted with compositions containing organosilicon compounds to prepare modified silica fillers. The compositions contain only organosilicon compounds which are monomeric dichlorosilanes and trialkoxysilanes. The treating compositions may be (i) mixtures or blends of dialkyldichlorosilanes, and trialkoxysilanes free of hydrocarbon or organofunctional groups reactive with silica surfaces, or (ii) mixtures or blends of substituted dialkyldichlorosilanes in which the substituted dialkyldichlorosilanes are free of hydrocarbon or organofunctional groups reactive with silica surfaces, and trialkoxysilanes free of hydrocarbon or organofunctional groups reactive with silica surfaces. These mixtures and blends contain dialkyldichlorosilanes and trialkoxysilanes in a weight ratio of 1:0.1 to 1:2, respectively.
