Disclosed is a self-invertible inverse latex comprising an aqueous phase containing: a. a crosslinked anionic polyelectrolyte (P) consisting of: - at least one monomer unit derived from 2-methyl-2-[(1-oxo-2-propenyl) amino] 1-propanesulfonic acid in the form of a free or partially or totally salified acid; - at least one monomer unit derived from at least one monomer selected from the elements of the group consisting of acrylamide, N,N-dimethyl acrylamide, methacrylamide, N-isopropyl acrylamide, N-tert-butyl acrylamide; and - at least one monomer unit derived from a polyethylenic crosslinking monomer (AR); b. tetrasodium salt of glutamic acid, N,N diacetic acid. |
