Water-soluble, hydrophobically associating copolymers which comprise new types of hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether group with block structure comprising a hydrophilic polyalkylene oxide block which consists essentially of ethylene oxide groups, and a terminal, hydrophobic polyalkylene oxide block which consists of alkylene oxides with at least 4, preferably at least 5 carbon atoms.

Hydrophobically associating copolymers

Mixtures comprising in which the variables are each defined as follows:Ris selected from C-C-alkyl and hydrogen,A is the same or different and is selected from C-C-alkylene,n is in the range from 4 to 40, and

Mixtures comprising branched oligomeric or polymeric compounds, and preparation and use thereof
