    Abstract: A description is given of paper or cardboard packaging made from recycled paper with mineral oil contamination, the packaging having a barrier layer which can be produced by applying an aqueous polymer dispersion comprising a copolymer which is preparable by emulsion polymerization of C1 to C4 alkyl (meth)acrylates, acid monomers, such as acrylic acid or methacrylic acid for example, 0-20% by weight of acrylonitrile and 0% to 10% by weight of further monomers, the glass transition temperature of the copolymer being situated in the range from +10 to +45°C. The barrier layer may be located on one of the packaging surfaces, or may form one of a plurality of layers in a multi-layer packaging coating, or may be located as a coating on one side of an inner pouch situated within the packaging.

    Abstract: Process for preparing polymer powder from an aqueous polymer dispersion with water-soluble compounds, the fraction of such compounds being smaller than that of said aqueous polymer dispersion and being based on the polymer present in the form of polymer particles insoluble in water, which comprises subjecting the aqueous polymer dispersion to membrane filtration in a first step of the process and to spray drying in a subsequent second step of the process.

    Abstract: The invention relates to an associative thickening agent that can be obtained by means of radical polymerization, to the production thereof, and to the use thereof in paper coating colors. The associative thickening agent is formed by (a) acid monomers, selected from ethylene unsaturated C3- to C8-carbolic acids, (b) associative monomers of the general formula H2C=CR1-COO-(EO)n­-(PO)-R2, where R1 is hydrogen or methyl, n is a number greater than or equal to two, m is a number from zero to 50, EO is an ethylene oxide group, PO is a propylene oxide group, and R2 is a C8-C30 or a C8-C30 alkaryl group, and (c) non-ionic copolymerizable monomers different from a) and b), wherein the reaction product has been reacted with initiators forming non-ionic radicals after the polymerization.
