    摘要: 1-[2,2-bis(trifluoromethyl)-3,3,4,4,5,5,5-heptafluoropentyl]-3,5-diaminobenzene and 1-[2,2-bis(trifluoromethyl)-3,3,4,4,5,5,5-heptafluoropentyl]-4-aminobenzene, as well as fluorinated polymers, preferably polyimides. The perfuuoroalkyl group of these amines is connected to the benzene ring through a tertiary carbon atom followed by a methylene group. This renders the amines more reactive than other amines, where the perfluoroalkyl group is connected directly to the benzene ring. The absence of hydrogen from the group containing the tertiary carbon atom which is adjacent to the perfluorinated groups, prohibits dehydrofluorination.
