ABSTRACT:
A fluorine-containing polyether compound having the following general formula:(where R1is a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or a phenyl group; X is a bromine atom or an iodine atom; l and m each are independently an integer of 10 or more; and l+m is 30-200) can be produced by reaction of a fluorine-containing dicarboxylic acid fluoride compound having the following general formula:(where l and m each are independently an integer of 10 or more, and l+m is 30-200) with an aromatic amine compound having the following general formula:[where R1is a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or a phenyl group, R2is a hydrogen atom or a group represented by the general formula —SiR3R4R5(where R3, R4and R5each are independently an alkyl group having 1 to 10 carbon atoms or a phenyl group); and X is a bromine atom or an iodine atom] preferably in the presence of pyridine or a tertiary amine compound such as triethylamine, etc.
