Abstract

Method of preparing strongly basic anion exchange resin intermediates, consisting of copolymerizing a monomer mixture comprising monovinyl aromatic monomer molecules and one or more aliphatic polyfunctional methacrylates having at least three methacrylate groups, thereby forming a copolymer crosslinked containing more than 50% monomeric units of the monovinyl aromatic monomer.
