摘要

PROBLEM TO BE SOLVED: To provide a novel conductive polymer usable as an overcurrent protection element.SOLUTION: A copolymer comprises a repeating unit derived from 3,4-bis(carbamoyloxy)thiophenes represented by the specified general formula (1) or general formula (2), and a repeating unit derived from a thiophene monomer. [In the specified formula (1), Rand Reach independently represent a C1-C12 alkyl group.] [In the specified formula (2), Rto Rrepresent a hydrogen atom or a C1-C3 hydrocarbon group.]
