Heat Resistant Poly(amide-imide)s Derived from N,N′-(4,4′-Pyromellitoyl)-bis-L-phenyl Acetic Acid and Aromatic Diamines: Synthesis and Properties
Six new heat resistant and optically active poly(amide-imide)s 5a–f were prepared by the direct polycondensation reaction of N,N′-(4,4′-pyromellitoyl)-bis-L-phenyl acetic acid 3 with various different diamines 4a–f in a medium consisting of triphenyl phosphite, N-methyl-2-pyrrolidone, pyridine and c...
