Suitable choice of monomer/nonsolvent and monomer plus solvent/nonsolvent ratios affords a very simple and convenient laboratory scale method for the synthesis of functionalized crosslinked polymers suitable as polymeric supports in a wide variety of applications. The method involves an initially homogeneous solution polymerization which, because of the presence of nonsolvents ultimately produces insoluble, particulate (i.e., nonswollen) resin. Advantages over the usual suspension polymerization processes include the absence of stabilizers and suspension agents and complete freedom to utilize water soluble or water insoluble monomers, or mixtures of the two. Reaction conditions must be determined experimentally for individual systems and a number of representative examples are given.
