| 主权项 | 1. A surface-modified silicon dioxide particle or silica sol obtained by reacting aqueous silica sol with at least one first modifier comprising at least one alkoxysilane and with at least one second modifier selected from the group consisting of halosilane, siloxane, and mixtures thereof, with water being removed from the reaction by azeotropic distillation prior to reaction with the first or second modifier, wherein the reactions with the first and second modifiers are carried out successively. | ||
