Fluorine-containing polyimide and production thereof

Abstract

Abstract PURPOSE:To provide a fluorine-containing polyimide having a small thermal expansion coefficient, dielectric constant and refractive index by reacting a specific tetracarboxylic acid anhydride containing fluorine-substituted groups with a diamine. CONSTITUTION:(A) An acid anhydride of formula I (R1 is a tetravalent organic group of formula II or III) is reacted with (B) a diamine of formula IV (R2 is p-phenylene, group of formula V, group of formula VI, etc.,) to provide (C) the objective fluorine-containing polyimide having repeating units of formula VII.
