a2) 1 to 50% by weight of a mixture of the repeating structural unit of the formula (1) and the repeating structural unit of the formula (2)
where R, R¹ and R² can be identical or different and are hydrogen or a linear or branched alkyl or alkenyl group having In each case 1 to 30 carbon atoms, and
b) 49.99 to 98.99% by weight of the repeating structural unit of the formula (3)
in which R³ is hydrogen, methyl or ethyl, Z is (C₁-C₈)-alkylene, n is an integer from 2 to 9 and X is Li⁺, Na⁺, K⁺, Mg⁺⁺, Ca⁺⁺, Al⁺⁺⁺, NH₄⁺, and alkylamines having alkyl substituents of (C₁-C₁₂)-alkyl or (C₂-C₁₀)-hydroxyalkyl, and c) 0.01 to 8% by weight of crosslinking structures having at least two olefinic double bonds.
