Porous polymeric resins, reaction mixtures and methods that can be used to prepare the porous polymeric resins, and uses of the porous polymeric resin are described. More specifically, the polymeric resins typically have a hierarchical porous structure plus reactive groups that can be used to interact with or react with a variety of different target compounds. The reactive groups can be selected from an acidic group or a salt thereof, an amino group or salt thereof, a hydroxyl group, an azlactone group, a glycidyl group, or a combination thereof.
A porous polymeric resin having a hierarchical porous structure comprising a first porous structure comprising a first set of pores having an average pore diameter less than 200 nanometers and a second porous structure comprising a second set of pores having an average pore diameter greater than 500 nanometers, the porous polymeric resin comprising the reaction product of an aqueous phase monomer mixture wherein all or substantially all of the monomers in the monomer mixture have a lipophilicity index no greater than 20, the monomer mixture comprising
