Abstract (en)
[origin: WO2005087816A1] The invention relates to an aqueous polymer dispersion containing effect materials with an average particle diameter for the dispersed particles of < 500 nm, said polymer particles comprising a core of a polymer matrix made up of at least one ethylenically-unsaturated monomer, on the surface of which an effect material is at least partly arranged, which is soluble in the monomers which form the particles of the polymer matrix, a method for production of such a polymer dispersion by mini-emulsion polymerisation of ethylenically-unsaturated monomers, whereby a mini-emulsion with a mean particle size for the emulsified particles of < 500 nm is produced by emulsification of ethylenically-unsaturated monomers in water in the presence of at least one effect material and one surface active material and the above is polymerised in the presence of at least one radical polymerisation initiator such that, firstly, only a maximum of 50 % of the monomers in the polymerisation zone polymerise and the effect materials migrate to the surface of the emulsified particles, the polymerisation being only complete after extensive or complete aggregation of the effect material on the surface of the generated polymer particles and use of the dispersion, or of a powder obtained by evaporation of water to stabilise the polymers against the effects of UV radiation, acids and heat, in cosmetic and pharamceutical formulations, in paint coatings, in the production of paper, leather and textiles and formulations for animal feedstuffs.
