Abstract

The invention relates to a pulverulent composition which can be produced by bringing a powder which comprises at least one inorganic binder into contact with from 0.01 to 10% by weight, based on the total mass of the composition, of a liquid component comprising at least one copolymer which can be obtained by polymerization of a mixture of monomers comprising (I) at least one ethylenically unsaturated monomer which comprises at least one radical selected from the group consisting of carboxylic acid, carboxylic acid salt, carboxylic esters, carboxamide, carboxylic anhydride and carboximide and (II) at least one ethylenically unsaturated monomer having a polyalkylene oxide radical, where the liquid component contains at least 1% by weight of the at least one copolymer and at least 30% by weight of an organic solvent. Furthermore, a process for producing the liquid component, the use thereof and also specific copolymers are disclosed.
