Abstract: A polymeric bead having radius R wherein the polymer comprises 0.3% to 20% by weight, based on the weight of the polymer, of polymerized units of one or more multifunctional vinyl monomer and 80% to 99.7% by weight, based on the weight of the polymer, of polymerized units of one or more monofunctional vinyl monomer, (a) wherein the polymerized units of multifunctional vinyl monomer have radial distribution factor MR of 0.9 to 1.1, and (b) wherein some of the vinyl groups in the polymerized units of multivinyl monomer are unreacted, and the unreacted vinyl groups have a radial distribution factor VR of 2.5 or higher.
