Novel side-chain-type sulfonated poly(arylene ether ketone) with pendant sulfoalkyl groups (SPAEK-xx) were synthesized by post-sulfonation method. Their structures were confirmed by FT-IR and NMR spectra. The all obtained membranes had excellent thermal stability and mechanical properties. The sidec

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
