Abstract	Nucleophilic aromatic substitution reaction of 5-amino-t-naphthol and also 4- aminophenol with bis(4-chlorophenyl)sulphone in N-methyl-2-pyrrolidone as solvent in the presence of K 2CO3 resulted in prepara-tion of two aromatic sulphone ether diamines. Polycondensation reaction of the prepared diamines with 4-chloroformylphthalic anhydride yielded thermally stable poly(sulphone ether amide-imide)s . The prepared polymers were characterized by conven- tional methods. Physical and mechanical properties of polymer including thermal behaviour, thermal stability, solution behaviour, solution viscosity, and modulus were studied . According to the obtained results, the prepared poly- (sulphone ether amide-imide)s showed physical and thermal properties that lied between corresponding poly(sulphone ether amide)s and poly(sulphone imides. This was an important aspect of structure-property relationships.
