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.

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.
