    Abstract: The invention relates to fine-particle, cationic, aqueous polymer dispersions, which can be obtained by emulsion polymerization of ethylenically unsaturated monomers in an aqueous solution of a cationic prepolymer as a dispersant, wherein first the cationic prepolymer is produced in a solution polymerization in a solvent partially or completely miscible with water in the presence of polymerization initiators by polymerizing (a) 15 to 40 wt% of a mixture of at least two different (meth)acrylate esters, each having an amino group and/or quaternary ammonium group, and/or (meth)acrylamides, each carrying an amino group and/or quaternary ammonium group, (b) 40 to 85 wt% of at least one optionally substituted styrene, (c) 0.5 to 5 wt% of at least one ethylenically unsaturated monomer containing acid groups, and (d) 0 to 20 wt% of at least one non-ionic, ethylenically unsaturated monomer different from (b), wherein the sum of (a) + (b)+ (c) + (d) = 100 wt%, the solution/dispersion of the prepolymer is then mixed with water, and subsequently in the aqueous solution of the prepolymer an emulsion polymerization of a monomer mixture of (i) 0 to 29 wt% of at least one optionally substituted styrene, (ii) 50 to 100 wt% of at least one C
    1 to C
    18 (methy)acrylate ester, (iii) 0 to 30 wt% of at least one vinyl ester of linear or branched C

    Abstract: A finely divided, cationic or amphoteric, aqueous polymer dispersion which is obtainable by emulsion polymerisation of ethylenically unsaturated monomers in the presence of a cationic or amphoteric protective colloid, wherein first the cationic or amphoteric protective colloid is prepared by polymerising a monomer blend in the presence of at least one first polymerisation initiator in an organic solvent, and is carried out in a pressurised reactor at a pressure of at least 1720 kPa and at a temperature of at least 150°C, which monomer blend comprises at least one ethylenically unsaturated monomer carrying an amine group,, to provide a resin, then combining the resin, with an acid and water, to form the cationic or amphoteric protective colloid, thereafter carrying out an emulsion polymerisation by introducing a monomer mixture into an aqueous medium containing said cationic or amphoteric protective colloid and at least one second polymerisation initiator, wherein said monomer mixture comprises at least one ethylenically unsaturated water insoluble monomer. The composition is useful as a sizing agent for paper.
