Method for preparing n-substituted nitrophthalimides |
| abstract |
Bis(nitrophthalimide)s can be prepared by effecting reaction in a phenolic solvent between an organic diamine and a nitrosubstituted phthalimide or a nitro-substituted phthalic acid. The bis(nitrophthalimide)s can be employed as intermediates for making polyetherimides by a nitro displacement reaction with a diphenoxide. |
