Abstract

The invention relates to a composition comprising olefinically functionalized siloxane oligomers derived from olefinically functionalized alkoxysilanes and optionally alkoxysilanes functionalized with saturated hydrocarbons, and also, optionally, a tetraalkoxysilane, which have not more than one olefinic radical on the silicon atom, and whose chloride content is reduced, and also to processes for preparing them and to the use thereof.
