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.

Abstract: The invention relates to a method for producing aqueous polymer dispersions containing colorants by radical aqueous emulsion polymerisation of ethylenically unsaturated monomers in the presence of radical-forming initiators. At least a proportion of the monomers is used in the form of an oil-in-water emulsion E1 whose disperse phase contains at least one oil-soluble colorant. The inventive method is characterised in that the disperse phase of E1 is essentially made up of colorant-containing monomer droplets with a diameter

Abstract: Method characterises samples (Si), especially those containing dissolved and/or suspended matter. It identifies the material, determining one or more of its characteristic values (Gji). The following stages are carried out: (a) the sample is centrifuged in an analytical centrifuge; (b) monochromatic light, preferably laser light, is directed into the sample; (c) light scattered from the sample is detected; (d) the substance(s) (Si) are identified by spectral evaluation of the inelastically-scattered fraction of the light detected; and (e) characteristic values (Gji) of the sample (Si) are determined by evaluation of its state as a result of centrifugation (after or during). Also claimed is an apparatus to characterise samples as described.
