Abstract: Described is an aqueous one-component coating composition comprising dispersed polyurethane and phyllosilicate. The polyurethane carries acid groups which are at least partially neutralized with a hydrophilic base selected from inorganic bases and organic mono-amines. The hydrophilic base has a water solubility at 20° C. of at least 150 g/l, preferably of at least 200 g/l. The composition can be used for providing oxygen barrier properties to a polymer film.

Abstract: Described is an aqueous coating composition comprising an aqueous dispersion of a radically polymerized addition polymer and phyllosilicate. The aqueous polymer dispersion has a particularly low electrical conductivity. The composition can be used for providing oxygen barrier properties to polymer films.

Abstract: Finely divided, cationic, aqueous polymer dispersion which is obtainable by emulsion polymerisation of ethylenically unsaturated monomers in an aqueous liquid containing a cationic prepolymer as a dispersant, wherein the cationic prepolymer is prepared in the presence of at least one polymerisation initiator by polymerisation of (a) from 15 to 45% by weight of at least one ethylenically unsaturated monomer comprising at least one quaternary ammonium group; (b) from 5 to 80% by weight of at least one optionally substituted styrene; (c) from 0 to 50% by weight of at least one C 1-12 alkyl (meth) acrylate; (d) from 0 to 10% by weight of at least one ethylenically unsaturated monomer comprising an acid group; (e) from 0 to 10% by weight of at least one ethylenically unsaturated monomer comprising an amine group; and (f) from 0 to 20% by weight of at least one non-ionic ethylenically unsaturated monomer differing from (b), (c) and (e), the sum of (a)+(b)+(c)+(d)+(e)+(f) being 100% by weight, in a first emulsion polymerisation in the presence of at least one non-ionic emulsifier, and thereafter, in the aqueous liquid containing the cationic prepolymer a second emulsion polymerisation is carried out, in the presence of at least one polymerisation initiator, of a monomer mixture comprising (i) from 10 to 70% by weight of at least one of an optionally substituted styrene or (meth) acrylonitrile; (ii) from 30 to 90% by weight of at least one CMS alkyl (meth) acrylate; (iii) from 0 to 30% by weight of at least one vinyl ester of linear or branched C1-30 carboxylic acids; and (iv) from 0 to 30% by weight of at least one non-ionic ethylenically unsaturated monomer differing from (i), (ii) and (iii), the sum of (i)+(ii)+(iii)+(iv) being 100% by weight, and the first emulsion polymerisation and/or the second emulsion polymerisation is optionally carried out in the presence of from 0 to 10% by weight of at least one polymerisation regulator. The polymer dispersions according to the present invention are suitable for use as sizing agents for paper, board and card board.

Abstract: Finely divided, cationic, aqueous polymer dispersions, method for the production thereof, and the use thereof The present invention relates to a finely divided, cationic, aqueous polymer dispersion which is obtainable by emulsion polymerisation of ethylenically unsaturated monomers in a continuous phase containing an aqueous liquid in which the emulsion polymerisation is carried out, in the presence of polymerisation initiators, of a combination of monomers comprising (a) from 0 to less than 60% by weight of at least one optionally substituted styrene, (b) from greater than 0 to 80% of at least one C1-C12-alkyl acrylate and/or at least one C1-C12-alkyl methacrylate, (c) from 0 to 10% by weight of at least one ethylenically unsaturated monomer comprising at least one acid group, (d) from 5 to 20% by weight of at least one ethylenically unsaturated monomer comprising a cationic group, and (e) from 0 to 50% by weight of at least one non-ionic ethylenically unsaturated monomer differing from (a), (b), (c), and (d), the sum of (a)+(b)+(c)+(d)+(e) being 100% by weight, and the aqueous liquid contains from 0 to 4% by weight based on the weight of the combination of monomers of at least one emulsifier, in which the emulsion polymerisation is carried out optionally in the presence of at least one terpene containing compound. Also claimed is a process or preparing the finely divided, cationic, aqueous polymer dispersion and the use of the finely divided, cationic, aqueous polymer dispersion for sizing paper, board and cardboard.
