  • New Reactive Surfactants for Emulsion

    New Reactive Surfactants for Emulsion

    Emulsion polymerization is a useful technique for preparing waterborne latexes used in coatings and inks. The polymerization reaction takes place in micelles in which the monomer droplet is stabilized by surfactants Figure 1. The surfactants, usually an anionic or a combination of anionic and nonionic surfactant, together with polymerization conditions, determine the particle size.
