Abstract

A reverse phase suspension polymerization process conducted using an ionic polymerizable material and a polymerization stabilizer of opposite ionic or potentially ionic charge is modified by including also a water soluble, substantially oil insoluble, ionic non-polymerizable compound having the same charge type as the polymerizable material and having at least one alkyl group containing at least 6 carbon atoms.
