Abstract: This invention relates to fluorine containing polyimide, a novel aromatic diamine which has a perfluoroalkyl radical and can be used as a raw material monomer of the polyimide, and a process for preparing the same. The polyimide comprise a requisite structural unit having one or more recurring structural units of the formula: such as the structural units of the formula Further, the present invention relates to a novel aromatic diamine which has a perfluoro radical and can be used as a raw material monomer of the polyimide, and a process for preparing the same. The present invention can provide polyimide which has an extremely low dielectric constant and is colorless, transparent and excellent in processability and heat resistance, and also provides an aromatic diamine which is useful as a raw material monomer of the polyimide or a raw material of other various engineering plastics.
