Novel tetracarboxylic dianhydride, polyimide derived from the same and compact constructed by the polyimide |
| abstract |
An objective of this invention is to provide a polyimide derived from a novel tetracarboxylic dianhydride, and a compact constructed by the polyimide. The polyimide is excellent in workability because it is excellent in solubility to various organic solvents and also has thermoplastic property, the polyimide having both low linear expansion coefficient and high optical permissibility (transparency). The aforesaid objective can be attained by a polyimide derived from a tetracarboxylic dianhydride represented by the following formula (1). |
