Producing metal-containing nanoparticles coated with polymers, useful e.g. for producing inks, comprises preparing anionic macro-initiator solution, adding monomer, polymerizing, and adding sulfide an

Producing metal-containing nanoparticles coated with polymers, comprises: preparing a solution of an anionic macro-initiator in an aprotic organic solvent; adding at least one anionic polymerizable monomer to the above solution; anionic polymerizing the above resulting solution at room temperature; adding an aliphatic or aromatic sulfide; adding a solution of at least one organo-soluble metal salt in an aprotic organic solvent; adding a homogenous reducing agent; precipitating the formed particles with an organic solvent; and separating and drying the particles. Producing metal-containing nanoparticles coated with polymers, comprises: preparing a solution of an anionic macro-initiator in an aprotic organic solvent; adding at least one anionic polymerizable monomer to the above solution; anionic polymerizing the above resulting solution at room temperature; adding an aliphatic or aromatic sulfide; adding a solution of at least one organo-soluble metal salt in an aprotic organic solvent; adding a homogenous reducing agent, if the redox potential of the organo-soluble metal salt is not sufficient to exclusively reduce to the metal by the aliphatic or aromatic sulfide; precipitating the formed particles with an organic solvent; and separating and drying the particles. An independent claim is also included for the metal-containing nanoparticles coated with polymers obtained by the above method.
