Chapter 18: Emulsion Photopolymerization
Published:10 Aug 2018
Photopolymerization in dispersed media is an interesting alternative to classical synthesis methods for elaborating polymers displaying high molar masses with high reaction rates in an environmentally friendly manner. This chapter presents emulsion radical photopolymerization initially stabilized with self-assembled (macro)molecules and giving submicrometric particles (10–500 nm) affording optical transparency in the UV–visible region. The effects of the chemical nature and concentration of the photoinitiator, of the monomer concentration and of light intensity on the kinetics of radical photopolymerization are investigated and compared to thermally initiated polymerization in disperse media. The possibility of using photoactive surfactants or developing photoinitiated controlled radical polymerization in emulsion is considered.
