The poly(aryl amide-imide) s having inherent viscosities of 0.39 - 1. 43 dL/g in N-methyl-2-pyrrolidinone at 30degreesC, were prepared by polymerization with aromatic diamines in N, N - dimethylacetamide and subsequent chemical imidization. All the polymers were amorphous, readily soluble in aprotic polar solvents such as DMAC, NMP, DMF, DMSO, and m-cresol, and could be cast to form flexible and tough films. The glass trsanition temperatures were in the range of 284 - 336degreesC, and the temperatures for 5% weight loss in nitrogen were above 468degreesC.
