PURPOSE: To obtain an electrically conductive polymer composition suitable as a shield for electromagnetic radiation, antistatic material, resistance heater, connector, etc., by compounding glass beads having diameter falling within a specific range and coated with Ni, Cu and/or Ag.
CONSTITUTION: Glass beads surface-coated with 5W50wt.%, preferably 10W40wt.% of at least one kind of metal selected from Ni, Cu and Ag are produced e.g. by catalyzing the surface of glass beads having diameter of 10W100μm and sphericity (major diameter/minor diameter) of preferably 1W2 e.g. with Pd, dispersing the beads in an aqueous solution of at least one kind of salt of a metal selected from Ni, Cu and Ag and adding a reducing agent to the dispersion to effect electroless plating. The obtained metal-coated glass beads are compounded in a polymer (e.g. acrylic polymer or urethane polymer) in an amount of 25W95wt.% to obtain the objective conductive polymer composition.
