Abstract:
Processes for producing polyether siloxanes are provided in which unsaturated polyethers are reacted with one or more SiH-functional siloxanes in the presence of Pt(0) compounds and tertiary amines Also, provided is the use of Pt(0) compounds and tertiary amines for producing polyether siloxanes and to the use of the polyether siloxanes thus obtained.
