Polyimides from 2,3,3',4'-biphenyltetracarboxylic dianhydride and aromatic diamines |
| 摘要 |
The present invention relates generally to polyimides. It relates particularly to novel polyimides prepared from 2,3,3',4'-biphenyltetracarboxylic dianhydride and aromatic diamines. These novel polyimides have low color, good solubility, high thermal emissivity, low solar absorptivity and high tensile strength.
