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 th e 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.

Abstract: Disclosed is a method for producing high dry-strength paper, pulpboard and cardboard by adding cationic, anionic and/or amphoteric starch as a dry-strength agent to the paper material, dehydrating the paper material to form sheets in the presence of cationic polymers as starch retention agents, and using cationic polymer retention agents to increase retention of dry-strength agents made from cationic, anionic and/or amphoteric starch during the production of paper, pulpboard and cardboard.
