Abstract (en)
[origin: WO2014095621A1] The present invention relates to water-soluble, hydrophobically associating copolymers, which are obtained in the presence of a non-polymerisable, surface-active compound and which contain novel hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether block, the polyether block containing a hydrophilic polyethyleneoxy block and a hydrophobic polyalkyleneoxy block, which consists of alkyleneoxy units having at least 4 carbon atoms. The monomers can optionally have a terminal polyethyleneoxy block. The invention further relates to a method for producing the copolymers and to the use thereof.
