Abstract (en)

[origin: FR2777011A1] The invention concerns water soluble polymers obtained by radical polymerisation in water-in-water emulsion of a mixture of substantially water soluble monomers containing a particular monomer having a polyethoxylated radical terminated by a hydrophobic group. Said polymers can be used as thickening agents for aqueous solutions.
