Abstract
There are disclosed metallized polymer particles comprising a crosslinked polymer with an insoluble content of at least 0.5% by weight. The crosslinked polymer bears nucleophilic groups capable of complexing at least one salt of a metal with an oxidation-reduction potential higher than -0.8 V. The crosslinked polymer particles have on their surface a metallic layer comprising at least one metal having an oxidation-reduction potential higher than -0.8 V and being in the zero valency state. Also disclosed are a process for obtaining such metallized particles via a chemical route, and a method of using these metallized particles in the manufacture of electrically conductive materials, including electrically conductive adhesives and paints.
