Abstract

The present invention relates to compositions containing polyether-siloxane copolymers which are based on branched SiH-functional siloxanes, where at least one of the polyether-siloxane copolymers has a radical —OR8 where R8=hydrogen or an alkyl radical having from 1 to 10 carbon atoms which is bound to a silicon atom, a process for producing polyurethane foam in which these compositions are used as foam stabilizers, polyurethane foams containing these compositions and the use of these polyurethane foams.
