摘要

There is provided a polymer including a unit represented by Chemical Formula (1): wherein R represents -A<SUB>1</SUB>-SO<SUB>2</SUB>R<SUB>1</SUB>; R<SUB>1w</SUB> and R<SUB>1X</SUB> are each independently a halogen atom or a hydrogen atom; R<SUB>1y</SUB> is a CH<SUB>3</SUB> group, a halogen atom or a hydrogen atom; A<SUB>01</SUB> is a substituted or unsubstituted aromatic ring structure or a substituted or unsubstituted heterocyclic structure; A<SUB>1</SUB> is a substituted or unsubstituted aliphatic hydrocarbon structure, a substituted or unsubstituted aromatic ring structure or a substituted or unsubstituted heterocyclic structure; R<SUB>1</SUB> is OH, a halogen atom, ONa, OK or OR<SUB>1a</SUB>; R<SUB>1a</SUB> is a substituted or unsubstituted aliphatic hydrocarbon structure, a substituted or unsubstituted aromatic ring structure or a substituted or unsubstituted heterocyclic structure.
