Abstract (en)
[origin: DE19707221A1] 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.
