Abstract (en)
[origin: WO2017050896A1] The present invention relates to the use of a copolymer as a dispersant for binder compositions based on calcium sulfate, the copolymer having a polymer backbone and sidechains bound thereto, and at least one ionizable monomeric unit M1 and at least one sidechain-carrying monomeric unit M2, characterized in that the copolymer has, in a direction along the polymer backbone, a non-random distribution of the monomeric units M1 and/or of the monomeric units M2.
