Water-soluble copolymers that are hydrophobicly associated, containing novel monomers that are hydrophobicly associated. The monomers comprise an ethylenically unsaturated group, as well as a block-shaped polyether group formed of a hydrophilic polyalkylene block, consisting substantially of ethylene oxide groups, and a terminal hydrophobic polyalkylene oxide block, consisting of alkylene oxides with at least 4, preferably, at least 5 carbon atoms. |
