摘要

Co- and terpolymers containing sulpho, water-soluble groups with a number average molecular weight of from 50,000 to 20,000,000 g / mol, which comprises: a) from 3 to 96 mol% of structural groups of the formula I : where R 1 = hydrogen or methyl, R2, R3, R4 = hydrogen, an aliphatic hydrocarbon radical having 1 to 6 carbon atoms, a phenyl radical optionally substituted by methyl groups, V = NH or oxygen and M = hydrogen, a cation of uni- or bivalent metal, ammonium or an organic amine radical, n = 1 to 5, a = 1/2 or 1 b) from 3 to 96 mol% of structural groups of formula II: wherein W represents = -CO-O- (CH2) x-, -CO-NR2- (CH2) x-, x = represents 1 to 6, R5 and R6 represent hydrogen or an aliphatic hydrocarbon radical having 1 to 20 carbon atoms, a cycloaliphatic hydrocarbon radical having 5 to 8 carbon atoms or an aryl radical having 6 to 14 carbon atoms, optionally substituted, and R1 and R2 have the above meanings, and / or c) of 0, 05 to 75 mol% groups componentesde Formula III in which Y is O, NH or NR5 R7 = R5 respectively R6, - (CH2) x-SO3 (Ma, X = halogen, (alkyl of C1 to C4) sulfate or (alkyl C1 to C4) sulfonate and R1, R5, R6, M, a and x have the above meanings, as stabilizers for aqueous building material systems and paints and coatings are water-based.
