Polyacrylic acid esters with ether sulfonate groups, obtainable by transesterification of polyacrylic acid alkyl esters with ether sulfonates of the general formula and optionally ethers of the general formula in which R¹ and R² are each hydrogen, methyl or ethyl, R³ is an alkyl or alkenyl radical having up to 30 carbon atoms or an alkylphenyl radical whose alkyl group has up to 30 carbon atoms, n and m in the average molecule each have a value from 1 to 200 and p is 2, 3 or 4.n n n The compounds show valuable properties as dispersants, thickeners, antistatic agents and as agents for improving the drying resistance of aqueous inks. |
