Herein, a novel approach for ATRP has been developed which enables the polymerization of vinyl monomers including Methyl methacrylate vinyl acetate and vinlyl private by using unimolecular ligand–initiator systems (ULIS) in the prensence of ppm amounts of copper. Well-controlled polymerizations were demonstrated for all systems,the experimental Mn values of the obtained polymers were consistent ith the corresponding theoretical ones, and the Mw/Mn values were comparatively controlled (1.3-1.7), showing the typical features of ‘‘living’’/controlled radical polymerization. In these study their ATRP behavior, the catalyst mediated ATRP for most of these reactions resulting in polymerization systems with controlled behavior.Successful chain extension of a PMMA macroinitiator to styrene demonstrated excellent chain-end functionality and living character. |
