Abstract:
1. A diarylamino group-containing copolymer comprising a molecular chain represented by the formula (1): and molecular chain terminals which are each independently a radical polymerization initiator residue or a hydrogen atom, the copolymer having a degree of polymerization of 3 to 500, wherein, in the formula (1), A and in the formulas (2) and (3), X 1 to X 25 each independently represents a hydrogen atom, a halogen atom, a C 1 to C 22 alkyl group, a C 1 to C 22 alkylthio group, a C 1 to C 22 alkoxy group which may be substituted with a halogen atom, an N,N-dialkylamino group in which each alkyl group is a C 1 to C 22 alkyl group, a phenyl group, or an N,N-diphenylamino group, J and in the formulas (4) to (7), R 1 to R 6 each independently represents a hydrogen atom, a C 1 to C 4 alkyl group, a carboxyl group, or an alkyloxycarbonyl group in which the alkyl group is a C 1 to C 22 alkyl group, R 7 and R 8 each independently represents a hydrogen atom or a C 1 to C 4 alkyl group, with the proviso that at least two of R 1 to R 4 represent a carboxyl group and at least one of R 5 and R 6 represents a carboxyl group, and m and n represent positive numbers.
