Abstract

A method for functionalizing a crosslinked polymer bead. The method comprises the steps of: (a) swelling the bead in a first solvent or solvent mixture to a volume from 200% to 310% of its volume when dry; and (b) contacting the bead with a functionalizing reagent in a second solvent or solvent mixture capable of swelling the bead to a volume from 200% to 310% of its volume when dry.
