摘要：A subject matter of the invention is a process for the preparation of particlescomprising at least one metal ion, which comprises the stage of bringing into contact aprecursor a metal cation, optionally partially hydrolyzed, with at least one water-solublecomb copolymer. Likewise, a subject matter of the invention is particles capable of beingprepared according to the process of the invention, said particles exhibiting a mean sizeof between 2 and 500 nm and preferably between 2 and 300 nm. Finally, it relates to theuse of such particles in the mechanical polishing of hard objects, in the preparation ofpigments or mixed ceramics for the electronic industry, in the reinforcing of polymericmatrices, in fungicidal or biocidal dispersions, in the scavenging of sulfur derivatives or thescavenging of unpleasant smells.
