ABSTRACT:
A process for the preparation of resin particles comprising: heating a mixture comprised of a free radical initiator compound, at least one stable free radical compound, at least one free radical polymerizable monomer compound, and at least one free radical polymerizable crosslinking compound; and cooling the mixture, wherein the resulting product resin particles are crosslinked and are comprised of polymerized monomers and at least one crosslinking compound, and wherein the particles have a narrow particle size distribution, a narrow pore size distribution, and a high monomer to polymer conversion.
