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 the production of moldings from nanoporous polymer materials, comprising the stages of a) preparation of a multiphase polymer mixture with domains in the range from 5 to 200 nm, b) impregnation of the polymer mixture with a blowing agent, where the solubility of the blowing agent in the phase forming the domains is at least twice as high as in the adjacent phases, c) expansion of the multiphase polymer mixture comprising blowing agent, by introducing the polymer mixture into a cavity and expanding it therein, thus obtaining the molding.

Abstract: Método para la preparación de polvos poliméricos, a partir de una dispersión polimérica acuosa, con una fracción más pequeña de compuestos solubles en agua en comparación con esta dispersión polimérica acuosa, referida al polímero presente en forma de partículas poliméricas insolubles en agua, caracterizado porque la dispersión polimérica acuosa se somete en un primer paso de proceso a una filtración de membrana y en un segundo paso de proceso a un secamiento por aspersión.

Abstract: The present invention relates to the production of a polymer powder with improved powder properties, and to its use as impact modifier for rigid polyvinyl chloride (PVC) applications. The impact modifier is composed of emulsion polymer particles which have a core-shell structure, where the shell is composed of a hard polymer and the core is composed of a soft, crosslinked rubber polymer.

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.
