## Abstract This study describes the preparation and characterization of new ionomer blend membranes containing sulfonated poly(ether imide) (SPEI) and poly(ether sulfone) (PES). Thermogravimetric analysis indicated that the obtained blend membranes were more thermally stable than the parent SPEI.
The design of high-performance pervaporation membranes for the selective removal of ethanol from ethyl t-butyl ether (ETBE) was performed by using the polymer blending method. Binary blends of cellulose acetate or cellulose triacetate with a specific copolymer, poly(vinyl pyrrolidone-co-vinyl acetat
