Patent ID: 11814463

Abstract:
The present invention addresses the problem of providing a fluorine-containing aromatic polymer; a method for producing the fluorine-containing aromatic polymer; etc. The problem can be solved by: a polymer having a monomer unit represented by formula (1) (wherein R1 in each occurrence is independently a halogen atom, NR11R12 (wherein R11 and R12 are independently a hydrogen atom or an organic group), or an organic group; n1 is an integer of 0 to 4; two R1s that can be present in the ortho-positions may form a ring together with two carbon atoms on the adjacent benzene ring, wherein the formed ring may have an organic group as a substituent; and L1 is a single bond, an oxygen atom, a sulfur atom, -L11-O—, —O-L12-O—, -L13-S—, or —S-L14-S— (wherein L11 to L14 are each independently an alkylene group optionally having one or more substituents); etc.
