摘要：
A sulfonated poly(aryl ether) (SPAE) having a poly(aryl ether) (PAE) main chain and a sulfonated phenyl group pendent from the main chain are useful in proton exchange membranes (PEMs), particularly for fuel cells. The pendent phenyl group can provide an easily sulfonable site that may be sulfonated under mild conditions, providing the ability to precisely control the sulfonic acid content of the SPAE.
