chain termination

in a chain polymerization
synonyms: irreversible chain deactivation, termination
https://doi.org/10.1351/goldbook.08946
Chemical reaction in which a chain carrier is converted irreversibly into a non-propagating species without the formation of a new chain carrier.
Notes:
  1. The recommended symbol for the rate coefficient for chain termination in a polymerization is \(k_{\rm{t}}\).
  2. The term 'chain deactivation' is often used to stress that, in contrast to chain termination, the formation of non-propagating species may be reversible; see chain deactivation.
