Abstract: The invention relates to a polymer, which can be obtained by co-polymerization of monomers, comprising at least one ethylenically unsaturated monomer that comprises at least one acid group and at least one ethylenically unsaturated monomer (II) having polyether groups with 5 to 35 repeating units and at least one ethylenically unsaturated monomer (III) having polyether groups with 45 to 150 repeating units, wherein the molar ratio of monomer (II) to monomer (III) is between 75:25 and 99.5:0.5. The invention further relates to the use of the polymer according to the invention as an additive for inorganic binding agent compositions, to a powdery composition comprising an inorganic binding agent, and to the polymer according to the invention.

Abstract: The invention relates to a pulverulent composition preparable by contacting a powder with 0.01 to 50 wt%, based on the overall mass of the composition, of a liquid component comprising at least one copolymer obtainable by polymerizing a mixture of monomers comprising (I) at least one ethylenically unsaturated monomer which comprises at least one radical from the series carboxylic acid, carboxylic salt, carboxylic ester, carboxylic amide, carboxylic anhydride, and carboxylic imide and (II) at least one ethylenically unsaturated monomer having a polyalkylene oxide radical, the liquid component comprising at least 1 wt% of the at least one copolymer and at least 30 wt% of an organic solvent, and the powder which is contacted with the liquid component comprising no inorganic binder. Further disclosed is a binder composition which comprises a pulverulent composition of the invention and an inorganic binder.
