Abstract: A composition comprises a fluorine-containing aromatic polymer, an epoxy compound and an initiator. Its use as film, laminate with polyimide or copper foils, copper-clad laminated board and adhesive film. The fluorine-containing aromatic polymer is preferably a fluorine-containing aryl ether polymer. The initiator is preferably a cationic initiator.

Abstract: The present invention has an object to provide a transparent resin material having a low water absorption ratio without deteriorating various properties such as transparency which transparent resin has and also having a controllable refractive index. The present invention provides a transparent resin material containing a polymer capable of forming a formed product having transparency, wherein the transparent resin material comprises a fluorine atom-containing polymer and/or compound and contains 0.3 to 35% by weight of a fluorine atom in 100% by weight of the formed product.

Abstract: It is an object of the present invention to provide a liquid composition for an organic-inorganic composite dielectric excellent in dispersibility of an inorganic dielectric in an organic polymer and exhibiting a high dielectric constant in the case where the composition is used for producing an organic-inorganic composite dielectric. The present invention is directed to a liquid composition for a composite dielectric, which comprises an inorganic dielectric and a fluorinated aromatic polymer.

Abstract: The present invention has an object to provide a fluorine-containing compound which can be used for applications such as additives making a transparent resin material low in a water absorbing ratio and high in water repellency without deteriorating of various properties such as transparency which the transparent resin material has, a fluorine-containing ester compound which is superior in properties such as heat resistance and low moisture(water) absorption property and can be suitably used in various fields such as a material for electronic information, a material for precision instruments and an optical material, a fluorine-containing aryl ester polymer, methods of producing the same.
