Abstract: Production of water-sol?ble crosslinked auxiliari?s for the papermaking industry by reacting(a) one equivalent of NH groups of a polyalkylene polyamine having from 15 to 500 alkyleneimine units with(b) from 0.001 to 0.08 mole of a reaction product obtained from a polyalkylene oxide having from 8 to 100 alkylene oxide units with epichlorohydrin, in aqueous solution at a temperature of from 20.degree. to 100.degree.C. The viscosity of an aqueous solution containing 20% by weight of the crosslinked auxiliaries is from 300 to 1,500 centipoises (20.degree.C).

Abstract: The invention relates to a method for producing paper by dehydrating, on a paper machine, paper pulp containing processing chemicals. According to said method, the paper machine wire is supplied, via a headbox, with a principal stream of paper pulp and a diluting stream consisting of returned water, containing at least 5 weight percent of the processing chemicals and accounting for between 5 and 35 % of the total headbox supply. The papers produced in this way have an excellent formation cross section and outstanding ash distribution.

Abstract: Aqueous pigment slurries which contain up to 80 % by weight of a finely divided pigment in dispersed form and from 0.1 to 5 % by weight of a polyalkylenepolyamine having a molecular weight of at least 300 or water-soluble reaction products of (a) polyalkylenepolyamines having a molecular weight of at least 300 and/or polyamidoamines grafted with ethyleneimine and (b) bifunctional or polyfunctional crosslinking agents which have a halohydrin, glycidyl, aziridine or isocyanate unit or a halogen atom as a functional group, the reaction products, in 25 % strength by weight aqueous solution at 20.degree.C, having a viscosity of at least 100 mPa.s, are used as an additive to the paper stock in the production of fillercontaining paper.

Abstract: In the prodn. of paper, paperboard and cardboard with high dry strength by adding a dry strength agent (I) to the pulp and dewatering, with sheet formation, the novelty is that (I) is an aq. soln. of mixts. of enzymatically degraded starches (II) with a viscosity of 20-2000 mPa.s (in 7.5% aq. soln. at 45 deg.C) and cationic polymers (III) derived from (a) diallyldimethylammonium chloride (IV), (b) N-vinylamine (V) or (c) N-vinylimidazolines of the formula (VI). R1 = H, 1-18C alkyl or C6H3R5R6; R5 and R6 = H, 1-4C alkyl or Cl; R2 = H, 1-18C alkyl, benzyl or glycidyl; R3 and R4 = H or 1-4C alkyl; X(-) = an acid gp.; which have a Fikentscher K value of min. 30 (In 5% aq. NaCl soln. at 25 deg.C and polymer concn. of 0.5wt.%).
