Abstract (en)
[origin: WO2020007466A1] The object of the invention are water-soluble copolymers based on a) 10 to 80 wt.% of one or more non-ionic, ethylenically unsaturated amide group-containing monomers, b) 10 to 60 wt.% of one or more hydrophobic, ethylenically unsaturated monomers and c) 0 to 30 wt.% of one or more ionic, ethylenically unsaturated monomers, wherein the amounts in wt.% add up 100 wt.%, with the proviso that the monomers a) are ≥ 95 wt.% of non-crosslinking monomers based on the total weight of the monomers a).
