Abstract
The invention relates to grafted copolymers comprising at least three sequences of distinct chemical nature, among which one or more sequence(s) for anchoring on solid particles, one or more sequence(s) of hydrophobic character and one or more sequence(s) of hydrophilic character. The invention also concerns their process of preparation, the compositions containing them, their use as agent for dispersing, stabilizing solid particles and/or emulsifying in an aqueous and/or organic medium, as well as use thereof for preparing pigmentary dispersions in aqueous and/or organic medium.
