New Catalysts for Controlled/Living Atom Transfer Radical Polymerization (ATRP)

摘要

Controlled/living radical polymerization (CRP) is one of the most rapidly developing areas of synthetic chemistry. Atom transfer radical polymerization (ATRP) is the only catalyzed method among CRPs. It enables synthesis of many well-defined polymers with controlled topology, composition and functionality. The design of new more efficient catalyst is a key challenge for ATRP. Several parameters are important for optimization of the ATRP catalyst. They include the proper control of ATRP equilibrium by adjusting redox properties and halogenophilicity of the transition metal complexes, their solubility and partition in biphasic systems as well as recyclability of the complexes, as described in this review.
