    Abstract: The invention relates to a method for mass-gluing paper, paperboard and cardboard by successively and continuously adding the aqueous dispersion of at least one type or reactive gluing agent and at least one type of retention agent into a laminar running pulp flow whose substance concentration is equal or less than 2 % by weight with respect to dry fibres, dewatering the paperboard and by forming sheets, wherein the inventive method consists in dosing the reactive gluing agent and the retention agent in the form of a turbulent flow into a pulp flow at a point located after a last shearing stage and prior to the beginning of a dewatering process.

    Abstract: Aqueous alkyldiketene dispersions which contain a C14-C22-alkyldi- ketene and from 1 to 10% by weight of a polymeric protective col- loid contain, as the protective colloid (a) copolymers of (1) N-vinylpyrrolidone and (2) at least one quaternized N-vinylimidazole or a substi- tuted quaternized N-vinylimidazole as polymerized units in a molar ratio of from 80:20 to 5:95 and have a K value of at least 20 (according to H. Fiken- tscher in 0.5 M aqueous sodium chloride solution at a polymer concentration of 0.1% by weight and at 25.degree.C) or (b) condensates which are obtainable by (1) partial amidation of polyethyleneimines with monocarbox- ylic acids and, if required (2) condensation of the partially amidated polyethyleneimines with at least bifunctional crosslinking agents Which have a halohydrin, glycidyl, aziridine or isocyanate unit or a halogen atom as a functional group to give crosslinked, amidated polyethyleneimines which have a viscosity of at least 100 mPa.s in 20% strength by weight aqueous solution at 20.degree.C, or mixtures of (a) and (b) and are used as engine size in the production of paper, board and cardboard and for rendering cellu- losic fibers water-repellent.
