Zusammenfassung: | The invention provides compositions containing a salt formed from an acid and from a base, wherein the acid is defined as a polycondensation product containing (I) at least one structural unit including an aromatic or heteroaromatic and a polyether side chain and (II) at least one phosphated structural unit including an aromatic or heteroaromatic, and polyethyleneimine as base, wherein the molar mass of the polyethyleneimine is greater than 500 daltons. Likewise provided is a process for producing these compositions and building product mixtures comprising the inventive compositions. The invention also provides for the use of the compositions as admixture agents, preferably as flow agents, for aqueous suspensions of binders based on calcium sulfate or for aqueous suspensions of (latently) hydraulic binders. |
