Method for producing coextruded multilayer aromatic polyimide film |
| abstract |
(57) [Summary] [Object] To provide a method for producing a multi-layer aromatic polyimide film having excellent adhesiveness between polyimide layers without using an adhesive. A first polyamic acid layer derived from the reaction of an aromatic tetracarboxylic dianhydride and an aromatic diamine and a reaction of 4,4'-oxydiphthalic dianhydride and (diaminophenoxy) benzene. Done second Is coextruded with at least one layer of polyamic acid to form a self-supporting multilayer polyamic acid film, which is heat treated to fully convert the polyamic acid layer to a multilayer polyimide film. In some cases, fine particles of an inorganic filler may be added to the polyamic acid solution to improve the properties of the multilayer film. Coextruded films are used to form single-sided and double-sided polyimide metal-clad laminates for use in flexible printed circuit applications. |
