ABSTRACT:
Metal-filled polyimide/polyepoxide blends, characterized by their improved electrical conductivity after curing over blends containing no polyepoxide, comprise carbinol-containing polyimides, conventional liquid polyepoxides, a solvent for the polyimide, noble metal powders (preferably silver), and optionally an amine catalytic curing agent. Conductivity improvements of 100-1000 fold or more are observed.
