NOVEL FLUORINE-CONTAINING DIAMINE AND FLUORINE-CONTAINING DINITRO COMPOUND, AND FLUORINE-CONTAINING POLYAMIC ACID AND FLUORINE-CONTAINING POLYIMIDE INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a fluorine-containing diamine for synthesizing a novel fluorine-containing polyimide having a low dielectric constant and a high glass transition point.;SOLUTION: The present invention provides a fluorine-containing diamine represented by formula [1] (where A is an organic group having a monocyclic or polycyclic, aromatic ring or heterocycle, R¹ independently represent a hydrogen atom, a methyl group, or a trifluoromethyl group, a is an integer of 1-4. -OC(CF₃)₂R¹ group and -NH₂ group independently binds to a carbon atom constituting the same or different aromatic ring or heterocycle, constituting the main chain in A).;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
