| Résumé : |
Several techniques have been researched to develop ways to control free radical polymerizations and terms like "Controlled Radical Polymerization" (CRP) or "living" free radical polymerizations have been used to describe the process. Thekey aspect in CRP is its ability to eliminate the termination of growing free radical chains. This facilitates the synthesis of polymers with low polydispersities, as well as co- and multiblock copolymers. This technology also allows well-defined polymer modification and grafting. Now, there is a family of nitroxide derivatives that can be applied to a wide range of free radical polymerizations to perform controlled radical polymer synthesis. This paper will examine the use of two nitroxide compounds, namely "SG-1" and "Monams", to synthesize acyrilic High Solids Coating (HSC) resins with low polydispersities. |
