Atom transfer radical polymerization (ATRP) employs the reversible transfer of halogen atoms between growing chains and a redox active transition metal catalyst. 1-3 In the key reaction, macromolecular alkyl halides are activated (ka) by reduction to free radicals and transition metals are simultaneously oxidized by accepting the halogen atom to its inner coordination sphere. 4 The free radicals generated are involved in three major reactions (neglecting other reactions such as transfer, etc., to simplify the analysis):
