Abstract: Preparation of metal-plated, extruded plastic comprises: melt blending and extrusion of a plastic mixture (comprising: thermoplastic polymer (A); metal powder (B) having an average particle diameter of 0.1-100 mu m and more negative normal potential in acid solution than silver; dispersant (C); and fibrous/particulate fillers or their mixture (D)); and contacting the extruded plastic object with an acid, neutral or basic metal salt solution through electrolessly or galvanically. Preparation of metal-plated, extruded plastic comprises: melt blending and extrusion of a plastic mixture (comprising 100 wt.% of the components related to the total weight: 5-50 wt.% of thermoplastic polymer (A); 50-95 wt.% of metal powder (B) having an average particle diameter of 0.1-100 mu m and more negative normal potential in acid solution than silver; 0-10 wt.% of dispersant (C); and 0-40 wt.% of fibrous/particulate fillers or their mixture (D)); and contacting extruded plastic object with an acid, neutral or basic metal salt solution through electrolessly or galvanically brought into contact , that metal having a more positive normal potential in a correspondingly acid, neutral or basic solution than component (B), where the plastic object is surface-activated in the non-molten state after the melt blending and extrusion step and before the contacting step. An independent claim is included for a metal-plated, extruded plastic object obtained by the process.
