Paragraph 0183-0186; 0213-0215, (2020/07/01)
The present invention includes a sulfonyl group (sulfonyl). A polyimide precursor and a manufacturing method thereof are provided to improve reactivity during polymerization and to remarkably increase molecular weight by including a novel diamine as a polymerization component. , It is possible to provide a polyimide film having improved mechanical and thermal properties while maintaining the optical properties of the polyimide containing a sulfonyl group.
