摘要：<p>Pulverulent composition prepared by contacting a powder comprising 0.01-50 wt.% liquid component having at least one copolymer, which is obtainable by polymerizing a mixture of monomers comprising (i) at least one ethylenically unsaturated monomer, preferably at least one carboxylic acid carboxylic acid salt, carboxylic acid ester, carboxylic acid amide, carboxylic acid imide or carboxylic acid anhydride, and (ii) at least one ethylenically unsaturated monomer with polyalkylene oxide residue, is claimed. The liquid component comprises 1 wt.% copolymer and 30 wt.% organic solvent. Pulverulent composition prepared by contacting a powder comprising 0.01-50 wt.% liquid component having at least one copolymer, which is obtainable by polymerizing a mixture of monomers comprising (i) at least one ethylenically unsaturated monomer, at least one carboxylic acid carboxylic acid salt, carboxylic acid ester, carboxylic acid amide, carboxylic acid imide or carboxylic acid anhydride, and (ii) at least one ethylenically unsaturated monomer with polyalkylene oxide residue. The liquid component comprises at least 1 wt.% copolymer and at least 30 wt.% organic solvent. The powder is contacted with the liquid component, which does not comprise an inorganic binder. Independent claims are also included for: (1) a binder composition comprising the pulverulent composition and an inorganic binder; (2) preparing the binder composition, comprising mixing the pulverulent composition with the inorganic binder and optionally further additives; and (3) using the binder composition for treating powder, which does not comprise inorganic binder, for accelerating the temporal development of the dispersing effect of the copolymer after addition of tempering water, where 0.01-50 wt.% liquid component is used based on the total weight of treated powder, and the treated powder is optionally mixed with inorganic binder before addition of the tempering water.</p>
