    The present invention proposes a polyczuboxylate ether-based additive having the general formula (I) for use as flow modifier in suspensions. The present invention further proposes a method for obtainment of such additive, wherein the method comprises the sequential steps of esterification of polyethylene glycol (PEG) with maleic anhydride (MA) and thus obtainment of a chemical product (PEGMA) and free radical polymerization in a mixture comprising acrylic acid (AA), 2-acrylamido-2 methylpropanesulfonic acid (AMPS) and PEGMA as reactants, further comprising water and an initiator, initial pH value of said mixture is within the range between 7.5 and 8.5, and any free oxygen is removed from the mixture throughout the free radical polymerization.
