Aqueous dispersions of reactive sizes comprise cationic polymers comprising vinylamine units as a protective colloid, the protective colloid comprising less than 0.0001% by weight, based on the protective colloid, of diketenes.

Aqueous dispersions of reactive gluing agents, method for the production and the use thereof

A paper size which comprises a stable aqueous dispersion of a reactive size, from 5 to 100% by weight, based on the reactive size, of a substantially linear nitrogen-comprising polymer having at least 3 mmol/g of basic nitrogen atoms, and from 1 to 50% by weight of cationic starch having a degree of substitution of at least 0.05 is described. The paper size has a good sizing effect and a stable viscosity.

Paper sizing agent

Aqueous alkyl ketene dimer dispersions which comprise at least 15% by weight of an alkyl ketene dimer and at least one water-soluble cationic starch, aluminum sulfate and at least one condensate of naphthalenesulfonic acid and formaldehyde or lignin sulfonic acid or in each case salts thereof, the dispersions comprising, based in each case on alkyl ketene dimer, from 2 to 50% by weight of aluminum sulfate, and in which the dispersions additionally comprise from 0.1 to 5% by weight of a saturated carboxylic acid having 1 to 10 carbon atoms, benzenesulfonic acid, p-toluenesulfonic acid and/or a mineral acid at an aluminum sulfate content of from 2 to 15% by weight, and the use of the dispersions as engine size and surface size for paper and paper products.

Alkylglucosides are prepared by acetalization of glucose with an equivalent amount or an excess of a C.sub.3 -C.sub.5 -alkanol in the presence of an acidic catalyst by a method wherein the acetalization is carried out in the presence of an alkali metal salt of a boric acid used in an amount which is equivalent to or in excess of the amount of the catalyst. The alkylglucosides obtained can be used directly, for example as solubilizers, in particular in the cosmetic sector, or can be reacted further to give higher alkylglucosides.
