Thermally polymerizable bisaryloxy-bisimido-bisphthalonitriles containing dimethylsilane, hexafluoroisopropylidene, ether, and keto groups: Synthesis, characterization, and NMR study

A proton‐NMR study of the condensation reaction (step 1) of 4‐(3′‐aminophenoxy)phthalonitrile (4‐3′APPN) (I) in an aprotic solvent with various aromatic dianhydrides demonstrated the formation of the corresponding bisamic acid within 5–10 min. There was no effect of the electron affinity of the used...
