The invention relates to a hydrosoluble copolymer comprising, in weight percent in relation to the total weight of the copolymer: between 1 and 40 of at least one cationic monomer; between 59.99 and 98 of at least one non-ionic monomer; and between 0.01 and 10 of at least one monomer of formula (I) wherein: R1 is a hydrogen atom or a methyl radical; Z is a divalent group -C(=O)-O-, or -C(=O)-NH-; -n is a whole number between 2 and 200; R2 is a hydrogen atom or a carbonated radical that is saturated or unsaturated, and optionally aromatic, linear, branched or cyclic, comprising between 1 and 30 carbon atoms, and between 0 and 4 heteroatoms selected in the group comprising O, N and S; the copolymer comprising a cationic charge density of between 0.05 and 3 meq/g. |
