Abstract:
A polymer containing a repeating unit expressed by General Formula (I): where Ar1 represents a substituted or unsubstituted aromatic hydrocarbon group; Ar2 and Ar3 independently represent a divalent group of a substituted or unsubstituted aromatic hydrocarbon group; and R1 and R2 each independently represent a hydrogen atom, substituted or unsubstituted alkyl group, or substituted or unsubstituted aromatic hydrocarbon group.
