Abstract

The invention relates to a composition containing olefinically functionalized siloxane oligomers which are derived from olefinically functionalized alkoxy silanes and optionally alkoxy silanes functionalized with saturated hydrocarbons and optionally a tetraalkoxysilane, at most comprising an olefinic group on the silicon atom having a reduced chloride content and the VOC content being lower with respect to the hydrolysable alkoxy-groups. The invention also relates to methods for the production thereof and to the use thereof.
