<p>The invention relates to a self-reversible reverse latex that includes: 50% to 70% of a cross-linked polyelectrolyte that is obtained by means of polymerization of a monomer of formula (I), with R1 being 8 to 20 carbon atoms and 1 = n = 30 for a neutral monomer, and a monomer comprising an acid function; 4% to 10% of a water-in-oil emulsifier; 1% to 10% of an oil-in water emulsifier including a nonzero mass ratio of a surface-active composition (C) that, for 100 mol%, contains = 10% to = 50% of a composition (CII) including, for 100%, 60% to 100% of a composition of formula (II), with R2 being an alkyl having 12 carbon atoms, T1, T2, and T3 being H or a (-CH2-CH2-0-)mi-H radical, and mi = 0 and = 10 with ?mi > 0 and = 10; = 50% to = 90% of a composition (CIII) including, for 100%, 60% to 100% of a compound of formula (III) or mixtures of (III) and (IV), with R2 being an alkyl having 12 carbon atoms, T4, T5, T6, and T7 being H or (-CH2-CH2-0-)mi-H, and mi = 0 and = 10 with ?mi > 0 and = 10; 15% to 45% oil; and 0% to 5% water. The invention also relates to the use of said self-reversible reverse latex as a thickener.</p> |
