  • Patent number: 6265529
    Abstract: Disclosed is an antistatic monomer-cast nylon (MC nylon) polymer. The MC nylon polymer includes graphite particles nonuniformly distributed in an MC nylon polymer structure. The graphite particles are partially agglomerated and form a micro-domain phase. The antistatic MC nylon has volume specific resistance of about 105 &OHgr;·cm to about 109&OHgr;·cm. Also disclosed is a method of producing antistatic MC nylon. A mixture comprising a monomer of the nylon and graphite is prepared and cast in a mold. The mixture is stirred to disperse the graphite and the monomer polymerizes to form an antistatic MC polymer.
