## Abstract Five new poly(amideβimide)s **8aβe** were synthesized through the direct polycondensation reaction of five chiral __N__,__N__β²β(pyromellitoyl)βbisβLβamino acids **3aβe** with 1,3βbis(4βaminophenoxy) propane **7** in a medium consisting of __N__βmethylβ2βpyrrolidone, triphenyl phosfite,
