Abstract

The efficiency of exchange between the mediating nitroxide moieties at the termini of growing polymer chains during “living” free radical polymerizations has been probed by a series of crossover experiments using functionalized unimolecular initiators. The design of appropriately substituted initiators permitted the synthesis of specifically functionalized model polymers which could be readily distinguished using high-performance liquid ...
