摘要：
Self-invertible inverse latex comprising, for 100% of its mass: a) - from 25% by weight to 80% by weight of a crosslinked anionic polyelectrolyte (P), resulting from the polymerization for 100% molar: i) - a proportion molar greater than or equal to 30% and less than or equal to 95% of monomeric units derived from at least one monomer comprising a strong acid function, free partially or totally salified； ii) optionally of a molar proportion greater than or equal to 10% and less than or equal to 65% of monomeric units derived from at least one neutral monomer； iii) optionally of a molar proportion greater than or equal to 5% and less than or equal to 65% of monomeric units originating from at least one monomer comprising a weak, free partially or totally salified acid function； and iv) - a molar proportion greater than 0% and less than or equal to 5% of at least one diethylenic or polyethylenic crosslinking monomer； b) - From 0.5% to 10% by weight of a terpolymer of stearyl methacrylate, pentacosaethoxylated behenyl methacrylate and N, N-dimethyl acrylamide, resulting from the polymerization for 100 mol%: from 80 mol% to 95%； mol% of stearyl methacrylate, from 2.5% molar to 10% molar N, N-dimethyl acrylamide, and from 2.5% molar to 10% molar pentacosaethoxylated behenyl methacrylate, c) - 5% by weight to 40% by weight of at least one oil, and d) - from 0.1% by weight to 40% by weight of water； process for its preparation and use as a thickener.Latex inverse auto-inversible comprenant pour 100% de sa masse : a) - De 25% massique à 80% massique d'un polyélectrolyte anionique (P) réticulé, issu de la polymérisation pour 100% molaire : i) - d'une proportion molaire supérieure ou égale à 30% et inférieure ou égale à 95% d'unités monomériques issues d'au moins un monomère comportant une fonction acide fort, libre partiellement ou totalement salifiée ； ii) - optionnellement d'une proportion molaire supérieure ou égale à 10% et inférieure ou égale à 65% d'unités monomériques
