Possibilities for Photoinduced Controlled Radical Polymerizations

摘要

The purpose of this paper is to present the possibilities and limitations of photoinduced controlled radical polymerizations for the synthesis of well-defined polymers. Although there currently exist only a few examples, photochemical initiation can be applied to the all conventional controlled/living radical polymerizations including iniferter, nitroxide mediated radical, atom transfer radical polymerization and reversible addition-fragmentation chain transfer polymerizations. The photochemical initiation not only enables the easy control of the polymerization under ambient temperature even for heat-sensitive monomers but also tends to minimize side reactions like chain transfer or depolymerization.
