Abstract: Paper, board and cardboard are produced from paper stocks which contain tacky impurities by the addition of surfactants and cationic polymers having a charge density of at least 1.5 meq/g (measured at pH 7) and a molar mass Mw of the cationic polymers of at least 15,000 and drainage of the paper stocks with fixation of the tacky impurities in the paper produced.

Abstract: Paper, board and cardboard having high dry strength are produced by the addition of cationic, anionic and/or amphoteric starch as dry strength agents to the paper stock and drainage of the paper stock with sheet formation in the presence of cationic polymers as retention aids for starch, and cationic polymeric retention aids are used for increasing the retention of dry strength agents comprising cationic, anionic and/or amphoteric starch in the production of paper, board and cardboard.

Abstract: The invention concerns amphiphilic graft polymers in which the graft base is a polymer containing at least 5 wt % of units of formula (I) and optionally units of formula (II), R1, R2 being H or C1-C6 alkyl, wherein (a) styrene, C1C2 alkylstyrene and/or vinyltoluene and optionally (b) other monoethylenically unsaturated monomers which can be copolymerized therewith are grafted onto the graft base in a weight ratio of between 1: 99 and 99: 1, and wherein the group (c) is optionally partially or completely cleaved off the graft polymers, forming amino groups. The invention also concerns processes for preparing and using the amphiphilic graft polymers as consolidating agents for paper, as fixing agents for disruptive water-soluble and water-insoluble agents in paper manufacture, as dispersants for inorganic and organic pigments, dyes, concrete and plant-protecting agents, as detergent additives, as coating material for fertilisers and plant-protecting agents, as floor-maintenance agents, as protective colloids for aqueous polymer dispersions, as thickeners for cosmetic formulations, as conditioners for skin-care agents and as a component of hair-cosmetic preparations and cosmetic preparations for oral hygiene.

Abstract: Paper 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.
