In this study, we investigated how styrene methacrylate (PSMA) copolymers neutralized with various cations affected the asphaltene dispersibility. In order to determine the effects of the type of cations of the ionomers on the dispersibility of asphaltenes, 14.1 mol% PSMA (Mw = 5000) copolymer was synthesized, and the acid groups of the PSMA were neutralized with Na+, Li+, and Cs+. It was found that the dispersibility of asphaltenes by the addition of the ionomers was better than that of the PSMA acid copolymer, regardless of the type of cations. On the other hand, the results also showed that the smaller the size of the cation, the better the dispersibility of asphaltenes.
