Two- and Three-Component Visible Light Photoinitiating Systems for Radical Polymerization Based on Onium Salts: An Overview of Mechanistic and Laser Flash Photolysis Studies

Figure 6

Plot of the square of the polymerization rate (■) and the radical yield (□) measured as the long-lived absorption at 425 nm by laser flash photolysis as a function of DPI concentration relative to the values in the absence of DPI. TEOA concentration is 0.027 M.
