Anion exchange polymers comprise a plurality of repeating units of formula (I). The polymer may be synthesized from a super acid catalyzed polyhydroxyalkylation reaction of monomers Ar1′ and X1′ to form a neutral precursor polymer followed by a Menshutkin reaction to convert the neutral precursor polymer to the anion exchange polymer with halide-based counterions, and then an ion exchange reaction to covert the anion exchange polymer with halide-based counterions to acetate (CH3COO−), trifluoroacetate (CF3COO−), propionate (CH3CH2COO−), or butanoate anion (CH3CH2CH2COO−) counterions. Anion exchange membranes and membrane electrode assemblies incorporating the anion exchange polymers are also described.
