Aliphatic polyimides (P-XBTA) having inherent viscosities of 0.4-1.4 dL/ g were readily synthesized by the high-pressure polycondensation of the salt monomers, composed of aliphatic diamines having various methylene chain lengths ( X Å 4-12) and 3,3,4,4-benzophenonetetracarboxylic acid (BTA), under

## Abstract We have synthesized a series of aliphatic‐aromatic polyimides by high pressure polycondensation of monomer salts derived from diaminoalkanes and diethyl 4,4″‐terphenyl‐tetracarboxylates. The polyimides, designated as P‐__n__TPE, were obtained with __n__, the number of methylene units in
