Water-soluble, hydrophobically associating copolymers that contain a new type of hydrophobically associating monomers. Monomers contain an ethylenically unsaturated group, as well as a polyester group with a block structure of a hydrophilic polyalkylene oxide block, which mainly consists of ethylene oxide groups, and a final hydrophobic polyalkylene oxide block, which consists of alkylene oxides containing at least 4 carbon atoms, mainly at least 5 carbon atoms. |
