Abstract: Water-in-oil polymer emulsions, characterised in that they contain water-soluble polymers having a mean particle size of from 0.1 to 20 mu m emulsified in a continuous oil phase comprising at least 50% by weight of an oil of vegetable or animal origin with the aid of from 0.5 to 15% by weight, based on the total emulsion, of an emulsifier mixture comprising a) from 5 to 95% by weight of a block or graft copolymer of the formula (A-COO)m-B, in which A is a hydrophobic polymer having a molecular weight of > 500 g/mol based on a poly(hydroxycarboxylic acid), B is a bifunctional hydrophilic polymer having a molecular weight of > 500 g/mol based on a polyalkylene oxide, and m is at least 2, and b) from 5 to 95% by weight of another water-in-oil emulsifier having a molecular weight of

Abstract: Disclosed is a method for producing condensation polymers of aspartic acid by means of condensation polymerization of aspartic acid at temperatures of 140 DEG C in the presence of, relative to aspartic acid, from 1 to less than 5 mol % phosphorous acid or hypophosphorous acid catalyst, and the use of the resulting condensation polymers of aspartic acid as additives in washing and cleaning products, amounting to 0.1 to 10 wt % relative to the washing and cleaning products.

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.
