The invention relates to anion polymers which can be obtained by (a) polymerizing olefinically unsaturated carboxy acids or the esters thereof with alcohols having 1-18 carbon atoms, optionally together with co-monomers of type (a1), dipropylene glycol diacrylate (DPGDA); (a2) tripropyleneglycol diacrylate (TPGDA); (a3) acrylamidomethyl propane sulfonic acid (AMPS); and/or (a4) acrylic acid ethyl esters (AE); (b) by esterifying the resulting intermediate products with a mixture of (bl) C1-C4-alkylpolyalkylene glycols and (b2) C6-C22-alkyl- and/or alkenyl polyalkylene glycols, and (c) by neutralizing the obtained esters with bases.
L'invention concerne de nouveaux polymères anioniques que l'on obtient (a) par polymérisation d'acides carboxyliques oléfiniquement insaturés ou de leurs esters avec des alcools ayant 1 à 18 atomes de carbone, éventuellement conjointement à des comonomères du type (a1) diacrylate de dipropylène glycol (DPGDA), (a2) diacrylate de tripropylène glycol (TPGDA), (a3) acide acrylamido méthyl propane sulfonique (AMPS) et/ou (a4) acrylate d'éthyle (AE), (b) par estérification des produits intermédiaires résultants avec un mélange constitué de (b1) alkylpolyalkylène glycols C1-C4 et de (b2) alkylpolyalkylène glycols C6-C22 et/ou alcénylepolyalkylène glycols C6-C22, puis (c) par neutralisation des esters ainsi obtenus avec des bases.
