The present invention relates to an electrically conductive polymer, and more particularly to an additive for enhancing electrical conductivity of the polymer and electrically conductive polymer composition containing the additive. The present invention provides a soluble self-orienting material (SOM) and an electrically conductive polymer composition containing the SOM. The SOM can be provided as a form of a monomer having an aromatic ring with various polarity, flexible side chain and hydrophilic dibasic acid, as a form of a complex consisting of the monomers linked by a hydrogen bond or a metal coordinate bond or as a form of a whole aromatic polymer having --NRCO--, --NROSO--(R: side chain including --H, --CO.sub.2H, --(CH.sub.2)nSO.sub.3H, --(CH.sub.2)nCO.sub.2H or -tert-butyloxycarbonyl) and --OCO--. And also, the composition of the present invention have higher electrical conductivity, in excess of 103 S/cm, than a conventional conductive polymer, and also have improved processability.
