PURPOSE:To obtain a novel substantially linear copolymer, having specific recurring units and high polymerization degree and capable of simultaneously exhibiting excellent electrochemical characteristics, mechanical strength and moldability and providing an electrically active polymer by doping with an electron acceptor. CONSTITUTION:A novel copolymer expressed by formula I (R<1> is H or 1-20C hydrocarbon residue; R<2> is H, 1-20C hydrocarbon residue, furyl pyridyl or methoxyphenyl; n and x are integers of >=2). The above-mentioned copolymer is obtained by, e.g. polycondensing a compound having a 3,6-carbazolediyl structure expressed by formula II as recurring units with an aldehyde expressed by the formula R<2>CHO or polymer thereof in an organic solvent, such as ethyl ether or chloroform, at 0-200 deg.C using a catalyst, such as sulfuric acid. The copolymer expressed by formula I is doped with an electron acceptor, e.g. iodine or nitric acid, to afford an electrically active polymer capable of exhibiting high electrical activity and carrying out oxidative and reductive reaction with excellent repeatability.
