Abstract:
Alkoxysilyl-functional polyether-siloxanes and processes for preparing them by noble metal-catalysed SiC coupling of hydrogensiloxanes having SiH groups with unsaturated polyethers bearing alkoxysilyl groups or by alkoxylation of polyethersiloxanes or polysiloxanes by means of epoxy-functional alkoxysilanes in the presence of double metal cyanide catalysts.
