Patent application numberDescriptionPublished
20090233110Use of polypeptides in the form of adhesive agents - A multilayered composite or coated substrate, comprising compounds of which at least 40% by weight are composed of alpha-amino acids linked via peptide bonds as adhesion promoters between at least two adjacent layers of the composite or between the coating and the substrate.09-17-2009
20100021754PREPARATION OF POLYMER DISPERSIONS IN THE PRESENCE OF INORGANIC POLYMER PARTICLES - Aqueous polymer dispersion obtainable by emulsion polymerization of monomers in the presence of inorganic polymer particles (inorganic particles for short) which are dispersible in the aqueous phase without surface-active assistants.01-28-2010
20100035065POLYMER DISPERSIONS CONTAINING HIGHLY BRANCHED POLYCARBONATES - The present invention relates to polymer dispersions which comprise highly branched polycarbonates, to a process for preparing them, and to their use.02-11-2010
20100055446PREPARATION OF POLYMER DISPERSIONS IN THE PRESENCE OF ORGANIC POLYMER PARTICLES - Aqueous polymer dispersion having a solids content greater than 50% by weight, obtainable by emulsion polymerization of monomers in the presence of organic polymers (organic particles for short) which are dispersible in the aqueous phase without surface-active assistants.03-04-2010
20100167063PAPER COATING COMPOUNDS CONTAINING SILICASOLS - Paper coating slips comprising at least one pigment and 07-01-2010
20100189994AQUEOUS DISPERSIONS OF CROSS-LINKED, TERTIARY ESTER GROUPS CONTAINING EMULSION POLYMERISATES AND WATER-ABSORBENT MATERIALS ON A CARRIER MATERIAL MADE THEREOF - Aqueous dispersions of crosslinked emulsion polymers comprising tertiary ester groups, comprising 07-29-2010
20110091733PAPER COATING COMPOSITION COMPRISING METAL SALT PIGMENTS AND HAVING A CONTENT OF AQUEOUS DISPERSIONS OF WATER-SOLUBLE COPOLYMERS - A paper coating slip which comprises metal salt pigments in an amount of at least 40 parts by weight, based on the total amount of pigments, and an aqueous dispersion of water-soluble copolymers is described. The copolymers are obtainable by free radical polymerization of ethylenically unsaturated, anionic monomers with ethylenically unsaturated, nonionic monomers in the presence of polymeric stabilizers for water-in-water polymer dispersions. The paper coating slips have good rheological properties and good water retention behavior in the coating of paper or cardboard.04-21-2011
20110143156METHOD OF PRODUCING PACKAGING HAVING FAT BARRIER PROPERTIES - A description is given of a method of producing packaging, the packaging surface being coated with a polyelectrolyte complex, and the polyelectrolyte complex being composed of at least one first polymer and at least one second polymer, the first polymer being an anionic polymer and the second polymer being a cationic polymer. The packaging is distinguished by good fat barrier properties.06-16-2011
