Abstract (en)

[origin: WO02081581A1] The invention concerns a liquid concentrate of mineral fillers comprising 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 consisting of 1) 5 to 40 wt. %, preferably 15 to 35 wt. %, more preferably still 20 to 30 wt. % of said anchoring sequence(s) consisting of a linear copolymer formed from at least two different monomer units including: a first ethylene monomer unit comprising at least a basic nitrogenous group, a second unsaturated ethylene monomer unit comprising an aromatic group, preferably a phenyl, the weight content in said first monomer units relative to said second monomer units being from 40 to 60 wt. %, preferably about 50 wt. %; 2) 25 to 90 wt. %, preferably 40 to 80 wt. %, more preferably still 50 to 70 wt. % of said organo-soluble hydrophobic sequence(s) to disperse the particles in apolar medium; and 3) 5 to 70 wt. %, preferably 15 to 30 wt. %, more preferably still 10 to 20 wt. % of hydrophilic sequences comprising a water-soluble polymer.
