Novel Soluble and Thermally Stable Category of Poly(sulfone ether imide)s

A novel sulfone ether diamine was synthesized via three-step reactions. After complete characterization, three different kinds of poly(sulfone ether imide)s were prepared by solution polycondensation of synthesized diamine with commercially available aromatic dianhydrides including pyromellitic dianhydride (PMDA), benzophenone tetracarboxylic dianhydride (BTDA), and hexafluoroisopropylidene diphthalic anhydride (6FDA). The structure of synthesized compounds, monomer, and prepared polymers was characterized using 1H-NMR and FT-IR spectroscopy and also elemental analysis method. Thermal behavior and stability, solubility, mechanical properties, and crystallinity of polymers were studied
