Abstract: Aqueous elutriations of fine-particled filling materials which are at least partially coated with polymers and which can be obtained by treating aqueous elutriations of fine-particled filling materials with at least one water-soluble amphoteric copolymer which can be obtained by copolymerization of (a) at least one n-vinylcarboxylic acid amide of formula (III), wherein R1, R2 = H or C1- C6-alkyl, (b) at least one monoethylenically unsaturated carboxylic acid with 3 -8 C atoms per molecule and/or the alkali metal, earth alkali metal or ammonium salts thereof and optionally (c) other monoethylenically unsaturated monomers which are free of nitrile groups, and optionally (d) compounds comprising two ethylenically unsaturated double bonds per molecule, and subsequent partial or full hydrolysis separation of groups CO-R1 from the monomers III polymerized inside the copolymer. The invention also relates to methods for the production of aqueous elutriations and the use thereof as additives to paper material in the production of paper containing filling materials, cardboard containing filling materials or paperboard containing filling materials by dewatering said paper material.
