Processes for controlled sulfonation of a polyaryletherketone comprise reacting a monomer of formula VIII with a monomer of formula IX to form a polyaryletherketone; and sulfonating the polyaryletherketone to form a sulfonated polyaryletherketone comprising structural units of formula IV wherein R<SUP>1 </SUP>is halogen, C<SUB>1</SUB>-C<SUB>10 </SUB>alkyl, C<SUB>3</SUB>-C<SUB>12 </SUB>cycloalkyl, or C<SUB>3</SUB>-C<SUB>15 </SUB>aryl; a is an integer from 0 to 4; Y is F, Cl, Br or a mixture thereof; m is 0 or 1; and Q is H, a metal cation, a non-metallic inorganic cation, an organic cation or a mixture thereof.
