Abstract
Organometallic reversible addition-fragmentation chain transfer reagents (RAFT reagents), processes of free radical polymerization employing the same and polymers with low polydispersity index obtained thereby. The process includes polymerizing at least one monomer with at least one initiator and at least one organometallic RAFT reagent to obtain polymers having terminal organometallic functional groups with low polydispersity index. In addition, the terminal organometallic functional group may be removed by subjecting the obtained polymer to elimination to provide the corresponding organic polymers.
