Sulfonated poly(phthalazinone ether sulfone ketone) (SPPESK) for proton exchange membranes were prepared by sulfonation of PPESK using fuming acid and sulfuric acid agent. The separation of SPPESK was carried out by precipitating in ether and then in acetone. The degree of sulfonation (DS) was deter

Three series of poly(aryl ether sulfone)s (PAESs) containing the phthalazinone moiety in the polymer backbone were synthesized by solution polycondensation of bis(4-chlorophenyl) sulfone with three commercial bisphenols and 4-(4-hydroxyphenyl)-2,3-phthalazin-1-one. Bisphenol-A, hydroquinone, and bis
