Versatile Route to Functionalized Block Copolymers by Nitroxide Mediated 'Living' Free Radical Polymerization

摘要

We have recently shown that replacement of TEMPO as the mediating nitroxide in 'living' free radical polymerizations by alpha-hydrogen derivatives leads to monomer selection and functional group compatability approaching that of ATRP based systems. The ability of these new alkoxyamines, such as 1, to mediate the homopolymerization of a wide variety of monomers should permit a much greater range of well defined random, block, and star copolymers to be prepared under simplified conditions.
