POLYMERIC DISPERSANT
The invention relates to a dispersant comprising a polymer obtainable by copolymerization of monomers including 5 to 80 mol % of a hydroxyalkyl acrylate phosphate and/or hydroxyalkylacrylamide phosphate (monomer 1), 0 to 20 mol % of a di(hydroxyalkyl acrylate) phosphate and/or di(hydroxyalkylacrylamide) phosphate (monomer 2) and 1 to 80 mol % of a polyalkylene glycol-containing macromonomer comprising an alkene group (monomer 3). Further disclosed is a process for preparing the polymers of the invention and the use thereof as dispersants in calcium sulphate-containing compositions. A further aspect of the invention is a process for producing shaped gypsum bodies, and also shaped gypsum bodies, more particularly gypsum plasterboards and self-levelling screeds, comprising the dispersant of the invention.
