In this manuscript, a hyperdispersant IBOMA-MPEGA-DMAM (IMD) has been synthesized using isobornyl methacrylate (IBOMA), polyethylene glycol monomethyl ether acrylate (MPEGA), and N, N-dimethyl acrylamide (DMAM) as monomers via a free radical polymerization method, which is used to improve the dispersibility of an aqueous dispersion system of carbon black. The molecular structure and performance stability of IMD were investigated through comprehensive characterizations of FTIR, GPC, particle size distribution and TEM. When the molar ratio of the monomers IBOMA:MEPGA:DMAM is 5.5:8.3:9.7, the obtained hyperdispersant shows good dispersibility. When the optimal dosage of dispersant IMD was 8%, the viscosity of carbon black slurry was as low as 18.6 mPa·s and the average particle size of carbon black was 275 nm. Furthermore, the stability of the prepared carbon black slurry was better than that of the two commercial dispersants.
