Abstract: The invention relates to a mixture composition having dispersing properties, containing copolymers based on unsaturated mono or dicarboxylic acid derivatives and oxyalkylene ethers as component I and water-soluble copolymers and terpolymers containing sulfo groups having an average molecular weight of 50 000-20 000 000 g/mol as component II. By combining both components, which can be respectively characterized by four different structural units, it is possible to obtain mixture compositions which can, more particularly, be used as dispersing agents for organic and/or inorganic pigments and fillers, in addition to known applications in the field of structural chemistry. In the field of structural chemistry, the mixture compositions are suitable for use on account of the dispersing properties thereof, particularly in ceramic systems and in water-based painting and coating systems.

Abstract: The invention relates to the use of water-soluble polymers, consisting of a) monoethylenically unsaturated monomers consisting of acidic groups in an acidic, partially or fully neutralized form and b) other monomers which can be copolymerized with monomers a) as a drying agent for the production of redispersion power and/or powdery polymer dispersing agents. The water-soluble polymers contain at least 20 wt. % monomers (a) and a maximum of 8O wt. % monomers (b) and are supplied to the production process in the form of aqueous solutions in amounts of up to 50 wt. % maximum, enabling powder, polymer products with a residual moisture of <2 wt. % to be obtained, particularly in spray drying processes, and which are added to mineral systems as dispersing agents in amounts of 0.05-5 wt. % or are used as building materials for the mineral binding of redispersion powder in adhesives or as a binders in their own right.
