Abstract: Paper and cardboard are produced by draining pulps, with sheet formation and drying of the sheets, by a process in which first (a) polyethyleneimines having a molar mass M w of more than 500,000 or polymers containing vinylamine units and having a molar mass of from 5000 to 3 million and then (b) cationic polyacrylamides or polymers containing vinylamine units, the molar masses M w of the polymers each being at least 4 million, are added to the pulps, and the pulp is then subjected to at least one shearing stage and is flocculated by adding bentonite, colloidal silica or clay.

Abstract: Graft polymers are obtainable by free radical polymerization of (A) monomers or monomer mixtures comprising (a) from 10 to 100% by weight of N-vinylcarboxamides of the formula (see formula I), where R1 and R2 are each H or C1-C6-alkyl, (b) from 0 to 90% by weight of other monoethylenically unsaturated monomers copolymerizable with the monomers (a) and (c) from 0 to 5% by weight of monomers having at least two ethylenically unsaturated, nonconjugated double bonds in the molecule in the presence of (B) polymers which contain at least 3 units of a C2-C4-alkylene oxide, and/or polytetrahydrofurans, in a weight ratio (A) : (B) of (95 to 10) : (5 to 90) , and, if required, subsequent elimination of some or all of the groups (see formula II) from the polymerized monomers (a) of the graft polymer with formation of units of the formula (see formula III) The graft polymers can be used as dry and wet strength agents, as fixing agents fear interfering substances and fillers, as retention aids and drainage aids in the production of paper and as promoters in the diketene sizing of paper, board and cardboard, as dispersants for pigments, as starch cationizing agents and as assistants in the production of tissue papers.

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.
