## Abstract Novel side‐chain‐type sulfonated poly(arylene ether) with pendant sulfoalkyl group copolymers (PSA‐SPAE‐6F) have been synthesized by direct copolymerization from a new sulfonated monomer, sodium 3‐(4‐(2,6‐difluorobenzoyl)phenyl)propane‐1‐sulfonate. The sulfonate content could be easily
## Abstract New membranes were prepared and evaluated as polymer electrolytes for PEMFCs. Polymers with PSU in the main chain and –C(O)(CF~2~)~3~SO~3~H in the side chain (PSU‐PSA) were synthesized by substitution of PSU‐Li and SFBF, followed by treatment with aqueous potassium hydroxide then sulfur
