Abstract

Abstract A polymer composition which is superior in processability, exhibits an extremely superior electroconductive characteristic when doped using an electron acceptor, and which comprises. (A) a copolymer represented by the following general formula (I): ##STR1## wherein R 1 is a hydrogen atom or a hydrocarbon residue having 1 to 20 carbon atoms, R 2 is a hydrogen atom, a hydrocarbon residue having 1 to 20 carbon atoms, furyl, pyridyl, nitrophenyl, chlorophenyl, or methoxyphenyl, n and x are each an integer not smaller than 2; and (B) one or more compounds selected from the group consisting of: polypyrrole compounds represented by the following general formula (II): ##STR2## wherein R 3 , R 4 and R 5 are each a hydrogen atom or a hydrocarbon residue having 1 to 20 carbon atoms, and p is an integer not smaller than 2; polythiophene compounds represented by the following general formula (III): ##STR3## wherein R 6 and R 7 are each a hydrogen atom or a hydrocarbon residue having 1 to 10 carbon atoms, and q is an integer not smaller than 2, and polyaniline compounds represented by the following general formula (IV): ##STR4## wherein R 8 , R 9 , R 10 and R 11 are each a hydrogen atom or a hydrocarbon residue having 1 to 10 carbon atoms, and r is an integer not smaller than 2.
