Patent ID: 7700706

Claim:
A process of making a polymeric bead comprising: (a) providing an organic phase; and (b) contacting said organic phase with an aqueous phase, under conditions of time, temperature and pressure effective to form the polymeric bead; wherein said organic phase comprises olefin monomers comprising one or more aryl-vinyl compounds, a cross-linking monomer, a functionalizing monomer having the formula: an initiator, and an organic solvent wherein R F is selected from substituted or unsubstituted C 1 -C 10 alkyl; wherein said organic solvent comprises one or more liquid hydrocarbons, and/or an alcohol having from five to twelve carbon atoms; said aqueous phase comprises water and a dispersing reagent; and wherein: the percentage by weight of olefin monomers initially present in total monomers is from about 60% to about 96%; the percentage by weight of the cross-linking monomer initially present in total monomers is from about 3% to 9.9%; the percentage by weight of the functionalizing monomer, having said formula, initially present in total monomers is from about 1% to about 20%; the percentage by weight of all of the monomers initially present in the organic phase is from about 33% to about 67%; the percentage by weight of the organic solvent initially present in the organic phase is from about 33% to about 67%; the percentage by weight of the liquid hydrocarbon present in the organic solvent is from about 0% to about 80%; the percentage by weight of the alcohol having from five to twelve carbon atoms initially present in the organic solvent is from about 20% to about 100%; and the percentage by weight of the dispersing reagent initially present in the aqueous phase is from about 0.01% to about 20%.
