Abstract: PCT No. PCT/EP96/00500 Sec. 371 Date Aug. 19, 1997 Sec. 102(e) Date Aug. 19, 1997 PCT Filed Feb. 7, 1996 PCT Pub. No. WO96/26318 PCT Pub. Date Aug. 29, 1997Aqueous alkyldiketene dispersions which contain a C14-C22-alkyldiketene and from 1 to 10% by weight of a polymeric protective colloid contain, as the protective colloid (a) copolymers of (1) N-vinylpyrrolidone and (2) at least one quaternized N-vinylimidazole or a substituted 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. Fikentscher in 0.5 M aqueous sodium chloride solution at a polymer concentration of 0.1% by weight and at 25 DEG C.) or (b) condensates which are obtainable by (1) partial amidation of polyethyleneimines with monocarboxylic 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 DEG C., or mixtures of (a) and (b) and are used as engine size in the production of paper, board and cardboard and for rendering cellulosic fibers water-repellent.
