Disclosed is a novel diamine having a structure of comprising an intramolecular imide group, and further comprising aromatic cyclic groups linked by an ester group to both sides of the imide group. When the novel diamine is used as a polymerizable component for preparing a polyimide, a polyimide film having remarkably improved mechanical and thermal properties while maintaining optical properties can be provided.
本发明涉及一种新型二胺,其结构包括一个分子内酰亚胺基团,并进一步包括通过酯基连接到酰亚胺基团两侧的芳香环状基团。当将该新型二胺用作聚合组分制备聚酰亚胺时,可以提供具有显著改善的机械和热性能,同时保持光学性能的聚酰亚胺薄膜。
