The influence of adsorption of polymers containing different functional groups on the dispersion behavior of pigment particles has been investigated in water. The polymers chosen are styrene-maleic anhydride copolymer modified with three different amines, tris (hydroxymethyl) amine, semicarbazide, and thiosemicarbazide of different hydrophilicity, to yield the corresponding grafted amic acids. The modified graft copolymers were characterized by Fourier transform infrared spectroscopy and H-nuclear magnetic resonance spectroscopy. Application of these amic acids as a dispersing agent to disperse titanium dioxide in water was studied. The Daniel flow method was used to assess the dispersing ability of these amic acids, and it was found that all the synthesized dispersants showed dispersion action on the pigment particles.
