The invention relates to the use of a weakly anionic copolymer and water-soluble, as a dispersing agent and / or aid for the grinding of pigments and / or mineral fillers in aqueous suspension giving on the one hand a low potential Zeta with aqueous suspensions of said fillers and / or pigments and secondly providing electro-steric stabilization of said suspensions. The invention also relates to said aqueous suspensions of pigments and / or fillers minerals and their uses in the fields of paper, such as manufacture or coating of paper, drilling muds used to prospecting or oil extraction. The invention also relates to the use of said dispersing agents and / or grinding aid in the fields of paints and plastics such as resins thermoplastics or thermosets. |
