摘要： A liquid concentrate of mineral fillers including an aqueous or organic solvent, mineral fillers useful for making paints, with a dry extract of mineral fillers not less than 65%, and a grafted copolymer of: 1) 5 to 40 wt. %, preferably 15 to 35 wt. %, more preferably 20 to 30 wt. % of anchoring sequences of a linear copolymer formed from at least two different monomer units including: a first ethylene monomer unit of at least a basic nitrogenous group, and a second unsaturated ethylene monomer unit of an aromatic group, preferably a phenyl, with the weight content of the first monomer units relative to th second monomer units is from 40 to 60 wt. %, preferably about 50 wt. %; 2) 25 to 90 wt. %, preferably 40 to 80 wt. %, more preferably 50 to 70 wt. % of organo-soluble hydrophobic sequences to disperse the particles in a polar medium; and 3) 5 to 70 wt. %, preferably 15 to 30 wt. %, more preferably 10 to 20 wt. % of hydrophilic sequences of a water-soluble polymer.
