Living radical polymerization and its new development

The paper is a review which deals with the living radical polymerization and its new development. By using stable free radical, such as nitroxides, as reversible terminating agents of the polymerization process, the propagation chains can be deactivated reversibly, so they are able to initiating and growing again in photoactiving and thermalactiving polymerization. The living radical polymerization can control the molecular weight, polydispersity, the chain-end, the architectural and structure of disterent polymers.
