<p>Modified silica fillers are prepared by contacting silica with blends or mixtures containing diorganodihalosilanes and monoorganotrihalosilanes in weight ratios of 1:0.1 to 1:2, respectively. While dialkyldichlorosilanes and monoalkyltrichlorosilane such as dimethyldichlorosilane and methyltrichlorosilane, respectively, are most preferred, the blends or mixtures may also comprise compositions containing n-propyltrichlorosilane, phenyltrichlorosilane, cyanopropyltrichlorosilane, and mercaptopropyltriethoxysilane.</p> |
