Side‐Chain Metallocene‐Containing Polymers by Living and Controlled Polymerizations

This review summarizes recent work on side‐chain metallocene‐containing polymers prepared by controlled and living polymerizations, which include living anionic polymerization (LAP), ring‐opening metathesis polymerization (ROMP) and controlled radical polymerization (CRP) such as atom transfer radical polymerization (ATRP), reversible addition fragmentation chain transfer polymerization (RAFT), and nitroxide‐mediated polymerization (NMP). The majority of efforts in the field are focused on side‐chain ferrocene‐containing polymers, while cobaltocenium‐containing polymers have recently started to draw attention. Future direction on the development of other metallocene‐containing polymers is discussed.
