چکیده:

A novel diamine with built-in sulfone, sulfide, and amide structure was prepared via three step reactions. Nucleophilic reaction of 4-aminothiophenol with 4-nitrobenzoyl chloride in the presence of propylene oxide led to preparation of N-(4-mercaptophenyl)-
4-nitrobenzamide(MPNB). The nitro group of this compound was reduced with hydrazine and Pd/C to afford 4-amino-N-(4-mercapto phenyl)benzamide (AMPB).Two moles of AMPB were reacted with bis-(4-chloro phenyl)sulfone to provide a novel sulfone sulfide amide diamine (SSAD). All the prepared compounds were characterized by common spectroscopic methods. The prepared diamine (SSAD) used to prepare related polyimides by reaction with different aromatic dianhydrides. The obtained poly(sulfone sulfide amide imide)s were characterized and their
properties were studied.
