Abstract: The invention relates to a pulverulent composition comprising, based on the overall mass of the composition, A) at least 20 wt % of a calcium sulfate-based binder and B) 0.01 to 4 wt % of 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 pulverulent composition being producible by a method in which a powder component comprising a calcium sulfate-based binder is contacted with a liquid hydrous component comprising less than 30 wt % of an organic solvent, comprising B), the liquid hydrous component being used in an amount of less than 20 wt %, based on the overall mass of the pulverulent composition, and the pulverulent composition comprising no hydraulic binder. A binder composition comprising an inventive pulverulent composition is also disclosed.
