| description | The present invention relates to thickener polymers which comprise the following structural elements 1-3: a) as structural feature 1 at least one betainic monomer unit according to the formula below with a proportion by weight of from 0.1 to 99.9% by weight, based on the copolymer in which the mutually independent definitions are as follows: m=integer 1; R1 H, C1-3 alkyl, -COOH; R2 H, C1-3 alkyl; R3=n- or isoalkylene of the formula -(CxH2x)-, in which x is an integer from 1 to 30; R4=-H, cycloalkyl, n- or isoalkyl, aryl; R5=n- or isoalkylene of the formula -(CyH2y)-, in which y is an integer from 1 to 30; A=-S-, -O-, -NR2, in which R2 H, C1-3 alkyl; b) as structural feature 2 at least one anionically charged monomer unit according to the following formula with a proportion by weight of from 0.1 to 99.9% by weight, based on the copolymer in which the mutually independent definitions are: l=integer 1; R1 H, C1-3 alkyl, -COOH; R2 H, C1-3 alkyl; R6=-OH, -OOH, -SH, -(CxH2x)-COOH, -(CxH2x)-SO3H, -N (R2)-(CxH2x)-SO3H, in which -(CxH2x)-=n- or isoalkylene and x is an integer from 1 to 30; c) optionally as structural feature 3 one or more non-ionic comonomer units with a proportion by weight of from 0 to 50% by weight, based on the copolymer. When compared with the prior art, the thickener polymers have increased shear resistance in aqueous formulations. |
