Abstract
Thiophene derivatives of the formula ##STR1## wherein R.sup.1 and R.sup.2 are certain specified substituent groups can be homopolymerized or copolymerized to form polymers which are electroconductive. These polymers find many uses, for example, as EMI/RF shielding materials, in electrochromic display systems, as antistatics, as ion and pH sensors, as battery electrode materials etc.
