Abstract: Paper, board and cardboard are produced by draining a pulp slurry in the presence of high molecular weight, water-soluble polymers of N-vinylamides as drainage aids, retention agents and flocculants. These polymers are particularly effective in a pulp slurry which has a high content of interfering substances and other phenolic compounds.

Abstract: Process for improving the printability of paper by a single- or two-sided application of aqueous coating materials consisting of a) 100 parts by weight of a finely dispersed pigment b) 5 to 70 parts by weight (based on solids) of a cationic aqueous polymer dispersion of a paper size and c) 0.01 to 10 parts by weight of a surfactant which interferes with the formation of the surface sizing and/or of a polymeric dispersant to the surface of the paper in a quantity of 0.5 to 4 g/m and drying the coated paper.

Abstract: Aqueous pigment suspensions which are added to the stock suspension during papermaking and contain, as a dispersant, from 0.1 to 2% by weight, based on the pigment, of a copolymer which contains, as copolymerized units, (a) from 40 to 95% by weight of an ester of (meth)acrylic acid with a saturated monohydric C1-C8-alcohol or with a saturated dihydric C2-C4-alcohol and (b) from 60 to 5% by weight of an ethylenically unsaturated C3-C5-carboxylic acid and has a K value of from 10 to 65 (determined according to H. Fikentscher in 1% aqueous solution in the form of the ammonium salt at pH 9 and at 20 DEG C.), their preparation and their use.

Abstract: In the process, an agent which confers dry strength and can be obtained by mixing enzymatically degraded starch having a viscosity of 20 to 2,000 m Pa.s (determined on a 7.5% strength solution in water at 45 DEG C) with cationic polymers which contain, in copolymerised form,… a) diallyldimethylammonium chloride… b) N-vinylamine or… c) optionally substituted N-vinylimidazolines as characteristic monomers, the K-value of the cationic polymers being at least 30, is added to the paper stock and the stock is dewartered, during sheet formation.
