PURPOSE: To form an electroconductive resin composition which can give a molding which can be freely colored and has a sufficient antistatic property, by adding a specified plasticizer and an electrolyte to a polymer component containing a polyvinyl chloride resin and an acrylonitrile/butadiene copolymer.
CONSTITUTION: This electroconductive resin composition is formed by adding a plasticizer (b) of the formula (wherein X is a 2W8 C aliphatic or alicyclic dibasic acid residue, R groups may be the same or different and are each a 3W15 C linear or branched alkyl group, A is a 2W4 C alkylene group, and m and n may be the same or different and are each an integer of 1W7, provided that the total number of carbon atoms of A and R is 5W17) and an electrolyte (c) are added to a polymer component (a) containing a polyvinyl chloride resin and an acrylonitrile/butadiene copolymer. An example of plasticizer (b) is a compound formed by an addition reaction of 1W7mol of ethylene oxide, 1W4mol of propylene oxide or 1W3mol of butylene oxide with propanol. An example of electrolyte (c) is zinc chloride.
