    Abstract: Use of fine-particled biocidal aqueous cationic dispersions of polymers as biocidal treatment agents for substrates at risk from microbes, preferably for fungicidal, bactericidal and/or algicidal treatments. The dispersions of polymers used are biocidal cationic dispersions of polymers which can be obtained from suitable monomers by emulsion polymerization and which contain biocidal cationically surfactant quaternary organic ammonium compounds, preferably tetra-substituted ammonium compounds of the formula (I) and/or alkyl- or alkenylpyridinium compounds of the formula (II), in particular in an amount of 0.1 to 20% by weight, based on the disperse polymer. The average particle diameter of the polymer particles in the biocidal cationic dispersions of polymers is preferably 0.02 to 0.5 .mu.m at a cationic activity of 1.5 to 600 .mu.mol per g of solid, measured at pH 7, and the solids content of the dispersions is preferably 3 to 40% by weight. The biocidal cationic dispersions are preferably used as treatment agents for the preservation of wood, for emulsion paint films and for polymer plasters or synthetic resin plasters, it being possible for the biocidal treatments which can be achieved to display surprising long-term biological actions.

    Abstract: The finely divided dispersions can be obtained by emulsion polymerisation from suitable monomers and contain biocidal, cationic- surfactant quaternary organic ammonium compounds, preferably tetrasubstituted ammonium compounds of the formula (I) and/or alkyl- or alkenylpyridinium compounds of the formula (II), in particular in an amount of from 0.1 to 20 % by weight, based on the dispersion polymer. The mean particle size of the polymer particles in the biocidal, cationic polymer dispersions is preferably from 0.02 to 0.5 mu m at a cation activity of from 1.5 to 600 mu mol per g of solid, measured at pH 7, and the solids content of the dispersions is preferably from 3 to 40 % by weight. The dispersions are used as finishing agents for microbe-endangered substrates, preferably for wood protection, for emulsion paints and for plastic or synthetic resin plasters, where the biocidal finishes which can be achieved may exhibit surprising long-term biological actions.

    Abstract: Unsaturated acetoacetic acid esters are suitable as comonomers in the polymerization of unsaturated compounds in an aqueous medium. Particularly suitable are acetylacetoxyalkyl-allyl ethers which may be synthesized in an easy manner and correspond to the formulae or Said allyl ether derivatives are especially prepared by reacting an allyl alcohol with an epoxide and reacting the resulting hydroxyalkyl-allyl ether with diketene. Both reaction steps are carried out at a temperature of from 0 DEG to 100 DEG C., preferably in the presence of a catalyst. The allyl ether derivatives may be copolymerized especially with vinyl compounds, such as vinyl esters, acrylic acid esters, olefins, vinyl halides and vinyl aromatic hydrocarbons.

    Abstract: Vinyl polymers with acetylacetoxy groups form the basis of polymer dispersions which are used as binding agent dispersions in paints, particularly suitable vinyl polymers are obtained by polymerizing an acetylacetoxy compound together with a least one further olefinically unsaturated compound, while using as acetylacetoxy compound an allyl ether derivative of the formula or The copolymerization is carried out in particular in emulsion at a temperature in the range of from -30 DEG to 200 DEG C. As comonomers there are used especially vinyl esters and (meth-)acrylic acid esters. The polymerization is commonly effected in the presence of a radical-forming initiator and optionally in the presence of emulsifiers and protective colloids.
