Abstract
A process for controlled coupling and chain extension, or atom transfer condensation polymerization, of molecules containing one or more radically transferable atoms or groups is provided, wherein transition metal compounds, optionally partially in the zero oxidation state, various ligands, counterions, and solvents are preferentially employed to preferentially give coupled and chain extended products that no longer contain a radically transferable atom or group.
