Aplicación

Potassium persulfate is used to initiate the polymerization of styrene to form monodispersed, surfactant-free polystyrene spheres. Potassium persulfate is used as an oxidant to generate 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation to measure the antioxidant activities of natural compounds.

Protocols

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.
