ABSTRACT:
Water-soluble and/or water-dispersible comb polymers comprising a polymer main chain and polyester side-arms which contain sulfonic acid groups and which are linked to the polymer main chain via ester groups, wherein said side-arms have been at least partially neutralized by sodium and lithium cations, wherein the molar ratio of lithium to sodium is between 0.1 and 50.
