Abstract

The invention relates to a catalytic system for the dehydrogenative condensation of polyorganosiloxanes with alcohols, consisting of at least one boron compound and at least one synergistically active compound, and to a process for converting polyorganosiloxanes, in which one hydrogen atom bonded to the silicon is replaced by an alkoxide radical using the inventive catalytic system.
