This invention relates to the injection moldable and extrusion type electrically conductive polymeric blend compositions having a viscosity at 200.degree. C. at 0.73 sec.sup.-1 of less than about 8.times.10.sup.5 poises. The compositions used for elastomeric articles include a neutralized sulfonated polymer; graphite fiber at a concentration of about 1 to about 50 parts by weight per 100 parts by weight of neutralized sulfonated polymer; and a preferential plasticizer at about less than 60 parts by weight based on 100 parts by weight of the neutralized sulfonated polymer. The composition may also optionally include fillers, oils and other additives. These blend compositions can be readily processed due to their superior rheological properties on conventional plastic fabrication equipment, especially on low and high pressure injection molding or extrusion equipment into electrically conductive articles having excellent physical and electrical properties.
