| titleOfInvention | Polyimide porous membrane and manufacturing method |
| abstract | (57) [Problem] To provide a porous membrane mainly composed of polyparaphenylenepyromellitimide and a method for producing the same. SOLUTION: A solution of a polyamic acid derived from an amide acid-forming compound of paraphenylenediamine and pyromellitic acid is cast on a smooth substrate, immersed in an aromatic hydrocarbon liquid, and the resulting polyamic acid porous membrane is imidized. Let it. It is preferable to perform the imidization after the isoimidization. |
