Abstract:
1. An ion exchange resin comprising the reaction product of a monomer mixture that is substantially free of a monomer having a lipophilicity index greater than 20, said 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; and (b) an ionic monomer in an amount of at least 35 weight percent based on a total weight of monomers in the monomer mixture, wherein the ionic monomer is of Formula I or a salt thereof, wherein Y is a straight or branched alkylene having 1 to 10 carbon atoms; and R is hydrogen or methyl wherein said ion exchange resin is in a form of macroporous particles having an average size of at least 20 micrometers and a surface area of at least 50 m
