An admixture including at least one copolymer having a backbone. The backbone including at least one electrically charged monomer. The at least one copolymer is a grafted copolymer having mean molecular weight within a range between 600 g/mol and 3000 g/mol on side chains of the grafted copolymer. An additive manufacturing ink, Filament of the additive manufacturing ink, and inkjet printing ink including the admixture.

Admixture and ink comprising the admixture

The present invention proposes a polycarboxylate 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.
