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.

    Abstract: The invention concerns aqueous alkyl diketene dispersions containing a C14-C22 alkyl diketene and 1-10 wt.% polymer-type protective colloid, and characterised by the fact that they contain as a protective colloid (a) copolymers of (1) N-vinylpyrrolidone and (2) at least one quaternised N-vinyl imidazole or a substituted quaternised N-vinyl imidazole, in a molar ratio of 80:20 - 5:95 and integrated by polymerisation, and have a K value of at least 20 (using the method of H. Fikentscher in 0.5 m aqueous cooking salt solution at a polymer concentration of 0.1 wt.% and a temperature of 25 ~C); (b) condensation products obtained by (1) partial amidation of polyethylene imines with monocarboxylic acids and, optionally, (2) condensation of the partially amidated polyethylene imines with at least bifunctional cross-linking agents containing as a functional group a halo-hydrine, glycidyl, aziridine or isocyanate unit or halogen atom to produce cross-linked amidated polyethylene imines with a viscosity of at least 100 mPas in a 20 wt.% aqueous solution at 20 ~C; or mixtures of (a) and (b). The invention also concerns the use of aqueous alkyl diketene dispersions as glue in the production of paper, pulp and cardboard and for the water-repellant finishing of cellulose fibres.
