Abstract
A method of forming a highly adsorptive polymer, which includes the steps of: (a) homogeneously mixing a solution of a monomer consisting exclusively of one or more types of polyunsaturated monomer, a monomer solvent, and an initiator, (b) polymerizing the monomers to form a polymer, wherein the monomer solvent is a solvent for the monomers and a non-swelling non-solvent for the polymer, and (c) removing the solvent from the polymer to form a dry powder.
