The present invention addresses the problem of providing a fluorinated aromatic polymer, a method for producing the fluorinated aromatic polymer, and others. The problem can be solved by: a polymer having a monomer unit represented by formula (1) (wherein R1's independently represent a halogen atom, NR11R12 (wherein R11 and R12 independently represent a hydrogen atom or an organic group), or an organic group in each occurrence; n1 represents an integer of 0 to 4; two R1's which can be present in the ortho-positions may together form a ring in conjunction with two carbon atoms on the adjacent benzene ring, wherein the ring may have an organic group as a substituent; and L1 represents a single bond, an oxygen atom, a sulfur atom, -L11-O-, -O-L12-O-, -L13-S- or -S-L14-S- (wherein L11 to L14 independently represent an aklylene group which may have at least one substituent)); and others. |
