Abstract
Process for preparing mineral particles in the form of colloids in aqueous dispersion of controlled size from a precursor, comprising: a) the step of putting the said precursor, which is a mineral salt of a metal cation, into aqueous solution; b) the complexation of the product obtained in a) with at least one water-soluble block copolymer having at least one complexing anionic hydrophilic block and at least one stabilizing nonionic hydrophilic block; and c) the partial or complete hydrolysis of the said precursor in order to obtain controlled growth of the mineral particles in the form of an aqueous dispersion. Use of said colloids, especially as reinforcing fillers for a polymer.
