Abstract: Additional cationic and/or amphoteric polymer(s) are added to the components containing the aqueous elutriate of fine particle fillers, before sheet formation. Materials added to the fibrous suspension do not include any ester of unsaturated carbonic acids with quaternated amino alcohols, as structural components. The cationic and/or amphoteric polymer(s) are added to the fibrous suspension directly after addition of components containing the aqueous elutriate of fine particle fillers. Cationic and/or amphoteric polymer(s) are added to the fibrous suspension in quantities of 0.0001 to 1 wt%, based on the dry matter content of the papermaking suspension. In paper made as described, the filler content is 3-45 wt%, based on the dry matter content of the papermaking suspension. An independent claim is included for paper made as described.

IPC: D21H21/18
Abstract: The invention relates to a process for producing paper, board and cardboard of high dry strength by separately adding a polymer comprising vinylamine units and a polymeric anionic compound to a paper pulp, dewatering the pulp and drying the paper products, which comprises using as polymeric anionic compound at least one copolymer obtainable by copolymerizing (a) at least one N-vinylcarboxamide of the formula in which R1 and R2 are H or C1- to C6 alkyl, (b) at least one monoethylenically unsaturated monomer comprising acid groups, and/or the alkali metal, alkaline earth metal or ammonium salts thereof, and if appropriate (c) other monoethylenically unsaturated monomers, and if appropriate (d) compounds having at least two ethylenically unsaturated double bonds in their molecule.
