  • Patent number: 9309152
    Abstract: A process for the production of a solid dispersant for a hydraulically binding composition includes the steps of: providing at least one first polymer, which is a comb polymer having a polymer backbone comprising carboxyl groups; providing at least one second polymer, which is a condensate of, at least, an aromatic compound and formaldehyde; or a lignosulfonate; preparing an aqueous solution comprising the first and the second polymer; and spray-drying the aqueous solution to obtain the solid dispersant.
