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.

Low chloride compositions of olefinically functionalised siloxane oligomers based on alkoxysilanes

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.

Mixtures, particularly low in volatile organic compounds (VOC), of olefinically functionalised siloxane oligomers based O alkoxy silanes

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 tetra alkoxysilane, at most comprising an olefinic group on the silicon atom and which has a reduced chloride content and a weight average molecular mass (Mw) of more than 315 g/mol.
