Abstract: A process for preparing polyether polyols by reaction of the following starting materials: a) one or more alkylene oxides and, if appropriate, carbon dioxide and also b) one or more H-functional starter substances, in the presence of a catalyst, in a reaction unit having a plurality of parallel layers A, B which are microstructured so that each layer has a multiplicity of channels which are arranged parallel to one another and form a continuous flow path from one side of the plate to the opposite side of this, wherein a distribution device for introduction of the starting materials and the catalyst is provided at one end of the channels of the layers A and a collection device for the reaction mixture is provided at the other end of these is proposed.

Abstract: The invention relates to water-soluble, hydrophobically associating copolymers containing novel hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether group with a block structure consisting of a hydrophilic polyalkylene oxide block, which essentially consists of ethylene oxide groups, and of a terminal, hydrophobic polyalkylene oxide block, which consists of alkylene oxides with at least 4 and preferably at least 5 carbon atoms.
