摘要：
An anionic polyelectrolyte resulting from the polymerization, for 100% by mass of: a) a mass ratio &gE；70% and &nlE；98.5% of monomeric units from a monomer with a strong acid function； b) a mass ratio &gE；0.5% and &nlE；10%, &mdash；either of a monomer of formula (1a) : R&mdash；(CH2)3-Si(CH2)2-[0-Si(CH3)2-]nO&mdash；Si(CH3)2&mdash；(CH2)3&mdash；R (1a), wherein R represents the monovalent radical: -(0-CH2-CH2-)x[0-CH2&mdash；CH(CH3)-]yO&mdash；C(&boxH；0)-CH&boxH；CH2；&mdash；or (Ib): Si(CH3)3-[0-Si(CH3)2-]m[0-Si(CH3)[(CH2)3&mdash；R]&mdash；]pO&mdash；Si(CH2)3 (Ib), c) a mass ratio &gE；1% and &nlE；20% of a monomer of formula (II) : CH2&boxH；CH(R1)-C(&boxH；0)-0-(CH2)n-CF3 (II), formula (I) wherein radical Ri represents a hydrogen atom or a methyl radical, and n is equal to 1, 2 or 3； d) optionally a mass ratio >；0% and &nlE；5% of monomeric units from a monomer of formula (III): R2&mdash；C(&boxH；0)-0-[(CH2&mdash；CH(R4)-0]m-R3 (III), e) optionally a mass ratio >；0% and &nlE；5% of a cross-linking monomer, method for its preparation and use as a thickener in topical compositions.
