A chain-growth polymerization whose propagating active centres are free radicals. Initiation creates active chains, propagation adds monomers while regenerating an active centre, and termination or transfer changes the population of growing chains.[ref]

Radical polymerization in which growing chain ends reversibly exchange between active radicals and dormant species. Keeping the active-radical concentration small can reduce bimolecular termination and narrow the molar mass distribution. Termination and chain transfer may still occur, so reversible deactivation alone does not guarantee ideal living polymerization.
Controlled radical polymerization based on reversible trapping of growing radicals by a nitroxide, forming dormant alkoxyamines. Initiation and end-group retention must be controlled to obtain predictable chain length.
