## Abstract Five new poly(amide‐imide)s **8a–e** were synthesized through the direct polycondensation reaction of five chiral __N__,__N__′‐(pyromellitoyl)‐bis‐L‐amino acids **3a–e** with 1,3‐bis(4‐aminophenoxy) propane **7** in a medium consisting of __N__‐methyl‐2‐pyrrolidone, triphenyl phosfite,
## Abstract __N__‐Trimellitylimido‐L‐leucine was reacted with thionyl chloride, and __N__‐trimellitylimido‐L‐leucine diacid chloride was obtained in a quantitative yield. The reaction of this diacid chloride with __p__‐aminobenzoic acid was performed in dry tetrahydrofuran, and bis(__p__‐amidobenzo
A series of new aromatic poly(amide-imide)s were synthesized by the triphenyl phosphite-activated polycondensation of the diimide-diacid, 2,5-bis(trimellitimido)chlorobenzene (I) with various aromatic diamines in a medium consisting of N-methyl-2-pyrrolidone (NMP), pyridine, and calcium chloride. Th
