Condensation product based on monomers comprises acid groups and/or their salts, where the monomers include (i) at least one monomer having an aldehyde group, (II) at least one monomer having ketone group, which carries at least one non-aromatic radical, and (iii) at least one monomer based on aromatic compounds, which does not carry aldehyde groups and ketone groups. Independent claims are included for: (1) preparing the condensation product by reacting monomers at a pH of 8-14; and (2) an anhydrous composition comprising 10-99 wt.% of condensation product and 1-90 wt.% of compound including polycarboxylate, lignin sulfonate, melamine formalhyde sulfonate, beta -naphthalene formaldehyde sulfonate, polyarylethers, phosphorylated polyalkoxylates, melamine condensates, sulfanilic acid-phenol resins, calcium nitrate, crystalline calcium silicate, phosphate, gluconate, sucrose, starch, triethanolamine, triisopropanolamine, diethanolisopropanolamine, ethanol diisopropanol, poly (hydroxyalkylated) polyethyleneamine, N,N-bis (2-hydroxypropyl)-N-(hydroxyethyl) amine, 1-(N, N-bis (2-hydroxyethyl) amino) propan-2-ol, N,N,N',N'-tri-(2-hydroxyethyl)-ethylenediamine, methyldiethanolamine, monoethanolamine, diethanolamine, monoisopropanolamine, diisopropanol and defoamers. |
