Abstract: PCT No. PCT/EP97/06857 Sec. 371 Date Jan. 27, 1999 Sec. 102(e) Date Jan. 27, 1999 PCT Filed Dec. 9, 1997 PCT Pub. No. WO98/29603 PCT Pub. Date Jul. 9, 1998Paper is produced by draining a paper stock containing process chemicals on a paper machine, a main stream of the paper stock and a dilution stream which consists of white water, contains at least 5% by weight of the process chemicals and amounts to 5-35% by volume of the total head box feed being fed via a head box to the paper machine wire. The papers thus produced have an excellent formation profile and an outstanding ash distribution.

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: Paper, board and cardboard are produced by draining a paper stock, containing un- desirable substances, in the presence of hydrolyzed homo- and/or copolymers of N-vinylformamide having a degree of hydrolysis of not less than 60% and a cationic retention aid. According to the invention, faster drainage and improved retention are obtained compared with the use of known fixing agents.

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: 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.
