This paper presents a novel procedure for the chemical synthesis of a melamine-formaldehyde resin, modified by sulfonation with sulfanilic acid. The product was characterized by chemical analysis, FTIR spectroscopy, UV-VIS spectroscopy and GPC chromatography. Experimental data confirmed the obtaining of three linerar oligomeric fractions of the melamine-formaldehyde polycondensate class, having the average molecular weights of 1143 Da, 768 Da, and 607 Da, respectively. The obtained product has potential uses in leather and fur industry, as pre-tanning or antistatic agent.
