Abstract:
1. An anion exchange resin that is a reaction product of a monomer mixture dissolved in an aqueous phase, the monomer mixture comprising (a) a N,N′-alkylenebis(meth)acrylamide crosslinking monomer in an amount greater than 25 weight percent based on a total weight of monomers in the monomer mixture; (b) an ionic monomer in an amount of at least 35 weight percent based on a total weight of monomers in the monomer mixture, each ionic monomer having a group capable of interacting with a negatively charged material, wherein the monomer mixture is free of an ionic monomer having a group capable of interacting with a positively charged material; (c) 0 to no greater than 1 weight percent based on the total weight of monomers in the monomer mixture of a hydrophobic monomer having a lipophilicity index greater than 20, wherein each monomer in the monomer mixture is a (meth)acrylate monomer, a (meth)acrylamide monomer, or derivative thereof; wherein said anion exchange resin is in the form of macroporous particles having an average size of at least 20 micrometers and a surface area of at least 50 m
