Abstract: Aqueous polymer dispersions and processes for preparing them are described. The polymer dispersions can be obtained by free-radically initiated emulsion polymerization of from 19.9 to 80 parts by weight of vinylaromatic compounds, from 19.9 to 80 parts by weight of acrylate monomers selected from among C1-C10-alkyl acrylates and C1-C10-alkyl methacrylates, from 0.1 to 10 parts by weight of ethylenically unsaturated acids and from 0 to 20 parts by weight of other ethylenically unsaturated monomers, wherein the emulsion polymerization is carried out in an aqueous medium in the presence of free-radical-forming initiators, seed latex and at least one carbohydrate compound in the form of a degraded starch. The polymer dispersions are particularly suitable for producing paper coating compositions.

Abstract: The invention relates to an aqueous polymer dispersion containing a polymer, which can be produced by a radically initiated emulsion polymerization from ethylenically unsaturated, radically polymerizable monomers, wherein the polymerization of the monomers is carried out in the presence of a specific molecular weight regulator composition. The molecular weight regulator composition contains at least one mercaptoalkylcarboxylic acid ester of a C2 to C4 carboxylic acid and at least one oligomeric compound of formula R1-X-(A-S-)n-A-Y-R2, where R1 and R2 denote H or CH3-(CH2)0-2-C(=0)-, X and Y denote an oxygen atom or a sulfur atom, A denotes a divalent C1- to C18-alkylene group, and n denotes a number from 1 to 8. The invention further relates to a method for producing the aqueous polymer dispersion. The polymer dispersion can be used as a binder, adhesive, sizing agent for fibers, for producing coatings or for producing paper coating compounds.

Abstract: Paper coating compositions comprise inorganic pigments and an aqueous polymeric dispersion comprising dispersed polymeric particles. The polymers are obtainable by polymerization of a first monomer that is liquid at room temperature, has a boiling point of at least 50°C and a glass transition temperature of at least 20°C as homopolymer, and a second monomer that is gaseous at room temperature, has a boiling point of below 0°C and a glass transition temperature of below -30°C as homopolymer. The dispersed polymeric particles have an average size of below 150 nm and a glass transition temperature in the range from -10 to +30°C.
