living cationic polymerization

https://doi.org/10.1351/goldbook.08987
Cationic polymerization in which chain termination and irreversible chain transfer are absent.
Note:
Cationic polymerizations, controlled cationic polymerizations and reversible deactivation cationic polymerizations should not be described as living if there is a non-zero probability of chain termination or irreversible chain transfer.
