Highly conductive polyoxymethylene resin composition containing carbon black

A highly conductive resin composition comprising:

• (a) 55%-89.95% by weight of a polyoxymethylene resin,
• (b) 5-15% by weight of a carbon black exhibiting a dibutyl phthalate absorption of 300-480 ml/100 g,
• (c) 0.05-10% by weight of an epoxy compound containing at least one glycidyl group or an epoxy compound obtained by oxidizing a compound having unsaturation to form an epoxy group therein, and
• (d) 5-20% by weight of a polyolefin copolymer of ethylene and an .alpha.-olefin of 3-6 carbon atoms, or a polyester copolymer having diol residues represented by formula (1) and dicarboxylic acid residues represented by formulae (2) and (4),
• --(O--R--O)-- (1)
• R is an aliphatic hydrocarbon residue of 2-12 carbon atoms, ##STR7## R.sup.1 is an ethylene group, a polymethylene group of 3-4 carbon atoms, or an alkylene group of 2-4 carbon atoms, ##STR8## Ph is an aromatic hydrocarbon residue, and the molar ratio of (2)/[(2)+(4)] being 5-100 mole %.
