Soap-free Emulsion Polymerization Stabilized by Inorganic Solids

2 Soap-free Emulsion Polymerization Stabilized by Inorganic Solids 

In fact, the ability of inorganic solids to impart colloidal stabilization to polymer latexes is not new. Interest in these systems emerged in the early 1990s with the pioneering work of Armes and co-workers on the synthesis of silica-vinyl (co)polymer latexes stabilized by ultrafine silica particles. However,
