Abstract
The invention relates to a process for preparing organofunctionally modified aerogels by gelling a water glass by means of polycondensation and then converting it, by drying while retaining the structure of the gel, to give an aerogel, which process comprises reacting the gel, before drying, with an at least bifunctional organic compound, at least one functional group serving as a bond to the aerogel, while the remainder are retained, to aerogels which are obtainable by the novel process, and to their use.
