Abstract: The invention relates to a paper sizing agent comprising a stable aqueous dispersion of a reactive sizing agent, 5 to 100 % by weight, with regard to the reactive sizing agent, of an essentially linear nitrogen-containing polymer with at least 3 mmol/g of basic nitrogen atoms, and 1 to 50 % by weight of cationic starch with a degree of substitution of at least 0.05. The paper sizing agent exhibits a good sizing effect and has a constant viscosity.

Abstract: 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.

Abstract: The invention relates to aqueous polymer dispersions containing alkenyl succinic acid anhydrides. Said polymer dispersions can be obtained by miniemulsion polymerisation of hydrophobic monoethylenically unsaturated monomers in the presence of alkenyl succinic acid anhydrides. The invention also relates to methods for producing such polymer dispersions by polymerisi ng hydrophobic monomers according to a miniemulsion polymerisation in the presence of at least one alkenyl succinic acid anhydride, and optionally one alkyl diketene. The invention further relates to the use of the aqueous polymer dispersions containing alkenyl succinic acid anhydrides obtained in this way, as pulp and surface sizing agents for paper, and for hydrophobing leather, natural and/or synthetic fibres, and textiles.
