Abstract

According to the present invention, a polymer is obtained by polycondensation of a fluorinated dicarboxylic acid derivative of the general formula (M-1) or an acid anhydride of the fluorinated dicarboxylic acid with a polyfunctional compound having two to four reactive groups corresponding in reactivity to carbonyl moieties of the fluorinated dicarboxylic acid derivative or acid anhydride.
