The synthesis, characterization, structural elucidation, and application of the dispersant obtained from the condensation of β -naphthalene sulfonic acid and formaldehyde are reported. The one-pot synthesis from naphthalene, sulfuric acid, and formaldehyde leads to reproducible polymers with 13 and 14 naphthalene nuclei. The 1H and 13C NMR spectra in D2O (representative spherical shape) and DMSO (representative rod-like shape) are reported. The belching technique led to excellent super pure material.
