摘要：
The invention relates to a method for producing a dispersant, comprising the following steps: a) providing at least one water-soluble polymer, comprising polyether groups, b) providing an inorganic component, comprising at least one phyllosilicate having an integer layer charge of 0, 1, or 2, c) producing an aqueous suspension, comprising the at least one water-soluble polymer, comprising polyether groups, and the inorganic component, comprising the at least one phyllosicilate, and d) spray-drying the aqueous suspension in order to obtain a solid. The invention further relates to the use of the dispersant according to the invention in an inorganic binder composition.
