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. The polymers were soluble in polar aprotic solvents and essentially amorphous. They showed glass transition temperatures in the range 310–350°C and decomposition temperatures of 450–460°C. Polymer films, fabricated by casting polymer solutions in DMA, showed tensile strengths in the range 70–90 MPa and moduli values between 3000–4000 MPa. © 1996 John Wiley & Sons, Inc.
