Preparation of Monodisperse Polymer Spheres

Monodisperse, surfactant-free polymer spheres for use as colloidal crystal templates can be easily obtained in reasonably large quantities. Typical synthesis methods for poly(methyl methacrylate) (PMMA) and poly(styrene) (PS) by emulsifier free emulsion polymerization are described below and yield spheres several hundred nanometers in diameter.
