Abstract
This invention relates to a new and improved quiescent polymerization process which produces spherical beads of polymer having excellent porosity and unusually high bulk density. The process comprises polymerizing discrete droplets of liquid monomer containing a monomer-soluble free radical type catalyst while suspended in an aqueous mucilage having plastic flow properties and in the presence of a nonionic surfactant having the proper Hydrophile-Lipophile Balance (HLB), such as, for example, sorbitan monooleate. The porous bead polymers have the advantage of providing for lower cost bulk shipping, better extrusion feed, and for easy monomer stripping.
