Organo-soluble polyimides from substituted dianhydrides |
| 摘要 |
The invention describes new biphenyl dianhydrides, and new polyimides and copolyimides made from the dianhydrides. The synthesized polyimides exhibit significantly enhanced solubility when the biphenyl dianhydrides are substituted, particularly at the 2 and 2' positions on the phenyl rings.
