POLYIMIDE POLYMER, POLYIMIDE FILM HAVING THE SAME AND POLYIMIDE LAMINATE HAVING THE SAME

摘要

A polyimide polymer, polyimide film and polyimide laminate plate including the same are provided. The polyimide polymer includes Formula (I), Formula (II) and Formula (III).; ;In Formula (I), Formula (II) and Formula (III), A is an aromatic group with fluorine, B, B′, and B″ are aromatic groups different from one another. B/(B+B′+B″), B′/(B+B′+B″), and B″/(B+B′+B″) are larger than 0. The polyimide film includes a film layer which includes the above polyimide polymer. The film layer optionally includes colorants or inorganic nanoparticles. Therefore, the thermal resistance and the transparency of the polyimide film are improved, and a polyimide film with high thermal resistance and different colors is available. The polyimide solution can also be applied on metal film to form polyimide laminate plate.
