Title: rare-earth-metal-mediated coordination-addition polymerization Long Title: IUPAC Gold Book - rare-earth-metal-mediated coordination-addition polymerization DOI: 10.1351/goldbook.09008 Status: current Definition Coordination-addition polymerization with propagation occurring within the coordination sphere of a rare-earth metal complex. Note The process may also involve non-rare-earth metal complexes with a sufficiently large coordination sphere (e.g., zirconium). Source - PAC, 2022, 94, 1093.
