TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The epoxy resin has 30-90 wt.% of aromatic cyclic structural units and/or alicyclic structural units. The epoxy resin is a novolak-type epoxy resin. The weight ratio of urethane-modified epoxy (meth)acrylate (B) and (meth)acrylate (C) in the conductive resin composition is 95/5-50/50. The conductive resin composition contains 50-90 wt.% of electroconductive filler (A), 6-18 wt.% of component (B), 2-8 wt.% of component (C) and 2-25 wt.% of component (D). Preferred Method: The (meth)acrylate (C) is obtained by reacting polyether polyol and (meth)acrylic acid. The polyether polyol has aromatic cyclic structural unit and/or aliphatic cyclic structural unit, and is an alkylene oxide addition product of polynuclear phenol-type compound. Preferred Monomer: The ethylenically unsaturated monomer (D) is an aromatic vinyl monomer. EXAMPLE - Epoxy methacrylate (B-1) (in wt.%) (80), methacrylate (C-1) (20), synthetic graphite K-100 (70) (with average particle diameter of 300 mum as electroconductive filler), styrene monomer (6.6), divinyl benzene DVB-96 (3.3) with purity of 96%, modified liquid compound of ISONATE143LJ (diphenyl methane diisocyanate, as polyisocyanate) (5.1), BIC-75 (organic peroxide initiator) (0.2), para-benzoquinone inhibitor (0.01) and carnauba wax as mold releasing agent (0.5), were blended, and a conductive resin composition was obtained. The obtained resin composition was packaged in a multilayered film. The resin composition was reacted for 2 days at 30degreesC, and maintained at room temperature. The resin composition was removed from the film. The resin composition had favorable handleability and flowability. Subsequently, a separator for fuel cell and a flat-molded product were produced using the conductive resin composition. The separator had favorable exterior. The molded product had electroconductivity of 10 mOMEGA.cm, bending strength of 41 MPa, heat deflection temperature of 217degreesC and hot water resistance of 3. The epoxy methacrylate (B-1) was synthesized using methacrylic acid, hydroquinone, Epiclon 860 (bisphenol A epoxy resin with epoxy equivalent of 245) and methyl imidazole. The epoxy methacrylate had hydroxyl value of 166 and aromatic cyclic structural unit content of 39 wt.%. The methacrylate (C-1) was synthesized using 2-hydroxy ethyl methacrylate, hydroquinone, tin octylate, addition product of bisphenol A/propylene BAP-2 and isophorone diisocyanate. The methacrylate (C-1) had hydroxyl value of 4, number average molecular weight of 910 and intramolecular aromatic cyclic structural unit content of 30 wt.%.
