Aqueous polymer latexes of film-forming copolymers obtainable by aqueous emulsion polymerisation of at least one non-ionic monomer M1; and The present invention also relates to a process for producing such polymer latexes and to the use of these polymer latexes as binders in waterborne coating compositions which contain at least one inorganic tannin blocking compound and to the use of such coating compositions for coating tannin-containing substrates such as wood or wood-based materials.

Aqueous polymer latex

The present invention relates to a process for producing an aqueous polymer dispersion of polymerized ethylenically unsaturated monomers M having a polymer content of at least 55 wt. % and a polymodal particle size distribution of the polymer particles of the polymer dispersion. The invention also relates to aqueous polymer dispersions obtained from this process as well as aqueous liquid compositions comprising at least one aqueous polymer dispersion and the use of such aqueous liquid compositions as binder.

Process for producing an aqueous polymer dispersion

The present invention provides very finely divided polymer dispersions obtainable by at least one two-stage emulsion polymerization, wherein

Finely divided aqueous multistage polymer dispersion, method for the production thereof, and use thereof as a binder

The present invention provides a process for preparing emulsion polymer particles of a hollow core/shell structure in the presence of a monomer plasticizer having a ceiling temperature less than 181&#xb0; C. wherein a polymerization inhibitor or reducing agent is not added to the aqueous emulsion of the core shell particles during the neutralization and swelling stage. The obtained core shell particles are useful in paints, paper coatings, foams, and cosmetics.
