    摘要: The invention relates to a composition comprising 5 - 50 % in wt. calcium silicate hydrate, 10 - 60 % in wt. of at least one water-soluble, acid-group containing polymer, comprising polyether groups and 5 - 40 % in wt. of at least one polyalkylene glycol ether. The invention also relates to a method for producing said composition and to cementitious mixtures comprising the composition. Another aspect of the invention is the use of the claimed composition in cementitious mixtures, for accelerating the temporal deconvolution of the dispersing effect of the acid-group containing polymers after the addition of the mixing water and the subsequent accelerated setting of the mixture.

    摘要: 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 analkene 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.
