## SYNOPSIS A series of poly(imide-amide)s were synthesized by interfacial condensation of carbomethoxy-iso/terephthaloyl chlorides (I) with aromatic diamines and polycyclic aliphatic diamines. Carbomethoxy-iso/terephthaloyl chlorides, containing approximately 50% para isomer and 50% meta isomer,
Novel poly(amide imide)s having inherent viscosities in the range 0.89-1.56 dL/g were prepared by the method of low temperature polycondensation in solution of N,N-dimethylacetamide (DMA) from aromatic diamines and a new monomer: N-[4"-(chloroformylphenyl) -4'-iminobenzoyl] trimellitimide chloride.
