An aqueous sespension, comprising;(1) water,(2) at least one mineral substance, and(3) a copolymer which comprises the following monomers in polymerized form:(a) at least one ethylenically unsaturated monomer having at least one carboxyl function,(b) optionally, at least one ethylenically unsaturated monomer having at least one sulphonyl function or phosphoryl function,(c) optionally, at least one ethylenically unsaturated monomer having no carboxyl function,(d) at least one ethylenically unsaturated oxyalkylated monomer terminating with a specified hydrophobic group,where the copolymer has a specific viscosity at most equal to 50. The suspension is useful in, for example, paper manufacturing and in the manufacture of coating colors for paper.
