Novel poly(arylene ether ketone) with fluorene pendants were synthesized and then sulfonated into a series of poly(arylene ether ketone)s with sulfonated fluorene pendants using chlorosulfonic acid. The sulfonated polymers were thereafter cast into membranes from their solutions. The properties of t
## Abstract A series of sulfonated poly(ether sulfone ether ketone ketone) (SPESEKK) with different degree of sulfonation (DS) are prepared by the postsulfonation of PESEKK using chlorosulfonic acid as sulfonating agent and concentrated sulfuric acid as solvent. The chemical structures of the polym
## Abstract Novel sideβchainβtype sulfonated poly(arylene ether) with pendant sulfoalkyl group copolymers (PSAβSPAEβ6F) have been synthesized by direct copolymerization from a new sulfonated monomer, sodium 3β(4β(2,6βdifluorobenzoyl)phenyl)propaneβ1βsulfonate. The sulfonate content could be easily
