Sulfonation of PEEK-WC powder (a glassy poly-ether ether ketone) has been performed at 80 • C for 3 h using H 2 SO 4 conc. (96%). The degree of sulfonation varied from 15 to 40%, depending on the reaction time. The sulfonated polymers (S-PEEK-WC) were used to prepare dense membranes for possible fue
