1. A sulfonyl-containing polymeric material comprising a reaction product of a reaction mixture comprising:
a) a precursor polymeric material comprising a polymerized product of a polymerizable composition comprising
i) a monomer mixture comprising
1) a monomer of Formula (I)wherein
each R1 is hydrogen, halo, alkyl, aryl, alkaryl, or aralkyl, wherein at least one R1 is hydrogen; each R2 is independently hydrogen, alkyl, aryl, alkaryl, aralkyl, combines with a R3 connected to a same carbon atom to form a cyclic alkyl, or combines with a R3 connected to the same carbon atom to form a cyclic alkyl that is fused to one or more carbocyclic rings; each R3 is independently hydrogen, alkyl, aryl, alkaryl, aralkyl, combines with a R2 connected to a same carbon atom to form a cyclic alkyl, combines with a R2 connected to the same carbon atom to form a cyclic alkyl that is fused to one or more carbocyclic rings, or combines with R4 connected to an adjacent carbon atom to form a carbon-carbon bond; and
each R4 is independently hydrogen or combines with R3 connected to the adjacent carbon atom to form a carbon-carbon bond;2) a second monomer that is styrene, styrene substituted with one or more alkyl groups, or a combination thereof, wherein the first monomer of Formula (I) is present in an amount up to 25 mole percent based on moles of the second monomer; andii) a free radical initiator; and
b) a sulfonyl-containing compound,wherein
the sulfonyl-containing polymeric material having at least one sulfonyl-containing group of formula —SO2R5 and up to a maximum of one group of formula —SO2R5 for each aromatic ring in the sulfonyl-containing polymeric material; R5 is —OH, —NH2, or —NR6-Q-N(R6)2; each R6 is independently hydrogen or alkyl; Q is a single bond, alkylene, or a group of formula -(Q1-NR6)x-Q2-; each Q1 is an alkylene; Q2 is an alkylene; and x is an integer in a range of 1 to 4. |
