Polymerisable thiophene monomers, their production and polymers prepared therefrom.

摘要

Thiophene derivatives of the formula wherein R<1> and R<2> are certain specified substituent groups can be homopolymerised 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.
