Claim 0:
1. A method of making a crosslinked polymer, comprising:
polymerizing a monomer comprising a (C0-6alkyl)acrylic acid, di(C1-6alkyl)acrylic acid, or a combination thereof; and a crosslinker comprising a (C1-6 alkylene glycol)-di(C1-6alkyl)acrylate, trimethylolpropane trimethacrylate, N,N′-methylenebisacrylamide, or any combination thereof; at a monomer:crosslinker ratio of from 1:9 to 14:1, in the presence of trimethylamine N-oxide and a solvent, to provide the crosslinked polymer,
wherein the crosslinked polymer comprises specific binding sites for trimethylamine N-oxide and a trimethylamine N-oxide absorption capacity of at least 0.5 mg/g.
