Claim 1:
2. The copolymer of claim 1, wherein in Chemical Formula 1, Ar2 is a group represented by Chemical Formula 2A, Chemical Formula 2B, Chemical Formula 2C, or Chemical Formula 2D:, wherein, in Chemical Formula 2A and Chemical Formula 2B
R1 and R2 are each independently hydrogen, a linear or branched hydrocarbon group having 1 to 14 carbon atoms, an aromatic hydrocarbon group having 6 to 14 carbon atoms, or an aromatic heterocyclic group having 3 to 25 ring-member atoms,
a and b are each independently an integer of 1 to 4, and
a link without * indicates a bond to the nitrogen of the arylamine side chain of Chemical Formula 1, wherein, in Chemical Formula 2C and Chemical Formula 2D,
Z1 is CRaRb, NRc, O, S, Se, or Te, wherein Ra, Rb, and Rc are each independently hydrogen, a linear or branched hydrocarbon group having 1 to 14 carbon atoms, an aromatic hydrocarbon group having 6 to 14 carbon atoms, or an aromatic heterocyclic group having 3 to 25 ring-member atoms, or Ra and Rb are joined to provide a spiro structure,
R1, R2, and R3 are each independently hydrogen, a linear or branched hydrocarbon group having 1 to 14 carbon atoms, an aromatic hydrocarbon group having 6 to 14 carbon atoms, or an aromatic heterocyclic group having 3 to 25 ring-member atoms,
a and b are each independently an integer of 1 to 4, and
a link without * indicates a bond to the nitrogen of the arylamine side chain of Chemical Formula 1.
