living anionic polymerization

https://doi.org/10.1351/goldbook.08980
Anionic polymerization in which chain termination and irreversible chain transfer are absent.
Note:
Anionic polymerizations, controlled anionic polymerizations and reversible-deactivation anionic polymerizations should not be described as living if there is a non-zero probability of chain termination or irreversible chain transfer.
