    Abstract: In order to prepare an antibacterial and fungicidal polymer dispersion, a polymer dispersion is mixed with an amount of a protective polymer which is dispersible in the polymer dispersion, said amount being sufficient to attain an antibacterial and fungicidal effect. The protective polymer comprises: between 3 and 60 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one C3 to C7 alpha, beta-monoethylenically unsaturated mono or dicarboxylic acid which is partially or completely neutralized or can be present as an anhydride, as component a); between 97 and 40 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one C1 to C20 alkyl(meth)acrylate, of a C1 to C20 carboxylic acid vinyl ester, of a vinyl aromatic containing up to 20 carbon atoms, of an ethylenically unsaturated C3 to C6 nitrile, of a vinyl halide or a non-aromatic C4 to C8 hydrocarbon and at least two conjugated double bonds or ethylene or propylene as component b); between 0 and 50 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one further ethylenically unsaturated monomer, as component c); and between 0 and 20 wt %, relative to the total weight of components a), b) and c) without metallic ions, of at least one cross-linking polyfunctional monomer, as component d). Between 1 and 100 mol % of the acid groups are converted into salts of at least one antibacterial and/or fungicidal metallic ion.

    Abstract: An aqueous polymer dispersion having a solids volume concentration of 50% by volume or more, obtained by free-radical aqueous emulsion polymerisation of free-radical-polymerisable monomers other than vinyl and vinylidine halides, with addition of an aqueous starting polymer dispersion having a certain diameter distribution of the starting polymer particles present therein, by the feed process.
