Abstract:
1. A linear, branched or crosslinked polyelectrolyte resulting from the polymerization, for 100 mol %: a) of a molar proportion greater than or equal to 60.00% and less than or equal to 90.00% of monomeric units resulting from at least one cationic monomer selected from the group consisting of: b) of a molar proportion greater than or equal to 9.95% and less than or equal to 35.00% of monomeric units resulting from at least one monomer comprising a free or partially or totally salified carboxylic acid function selected from the group consisting of acrylic acid, methacrylic acid, itaconic acid, maleic acid, and 3-methyl-3-[(1-oxo-2-propenyl)amino]butanoic acid, c) of a molar proportion greater than or equal to 0.05% and less than or equal to 5.00 mol % of monomeric units resulting from at least one monomer of formula (I): in which n represents, independently, a number between 1 and 50, A represents an unsaturated aliphatic monovalent radical comprising from 2 to 6 carbon atoms, R d) optionally of a molar proportion greater than 0% and less than or equal to 1% of a diethylene or polyethylene crosslinking monomer.
