Synthesis and characterization of a polyethersulfoneimide

Abstract

Two similar polyimide systems were synthesized and characterized. The only structural difference was a sulfide linkage in the anhydride derived portion of the first system versus a sulfone linkage in the second. Their physical, mechanical, melt-flow and thermal properties were determined and also their resistance to some of the more common solvents. The flow properties of these polyimides indicate them to have potential for melt processability.
