N2 - Copper powder dispersed poly-methyl methacrylic acid (acrylic resin, PMMA) composites (PMMA-Cu) were prepared by the solution cast method. The Cu addition at the critical volume fraction (15.0± 1.0 vol%Cu) drastically enhanced the electric conductivity from the insulator (10-14 Sm-1) to the electric conductor (105 Sm-1). The electric conductivity can be obtained by controlling the volume fraction of copper powders in PMMA polymers, as dilatation. The addition of 10 vol%Cu slightly enhanced the impact value of PMMA, whereas the remarkable decrease in the Charpy impact value was found at 25 ±5 vol%Cu. The high conductive PMMA-Cu composites (from 15 to 20 vol%Cu) with high impact value (5.5±0.5kJm -2), which was higher than that of dispersed nylono6 composites (2kJm-2) utilized for practical exteriors, were obtained without impact value decay by addition of small amount of copper powders.
