## Abstract A new kind of pyridine‐containing aromatic diamine monomer, 4‐phenyl‐2,6‐bis[4‐(4‐aminophenoxy)phenyl]‐pyridine (PAPP), was successfully synthesized by a modified chichibabin reaction of benzaldehyde and a substituted acetophenone, 4‐(4‐nitrophenoxy)‐acetophenone (NPAP), followed by a r
## Abstract A series of novel bis(phenoxy)phthalide‐containing poly(amide‐imide)s 3 were synthesized via direct polycondensation of 3,3‐bis[4‐(4‐aminophenoxy)phenyl]phthalide (BAPP) with various aromatic bis(trimellitimide)s 2 in __N__‐methyl‐2‐pyrrolidone (NMP) using triphenyl phosphite and pyridi
