Abstract
Sodium sulfonate-functionalized polyether ether ketone)s derived from Bisph enol A with a degree of sulfonation up to 2.0 were synthesized by aromatic nucleophilic polycondensation of various amounts of 5,5-carbonylbis(2-fluor obenzenesulfonate) (1), 4,4'-diflurobenzophenone (2) and Bisphenol A (2). C opolymers showed excellent thermal stability and good mechanical properties . The selectivity of water vapor over nitrogen of membranes prepared from c opolymers 3a and 3h was determined to be 3.43 x 10(6) and 1.05 x 10(7), res pectively.
