living radical polymerization

https://doi.org/10.1351/goldbook.08914

Radical polymerization in which chain termination and irreversible chain transfer are absent.

Notes:

Radical polymerizations, controlled radical polymerizations and reversible-deactivation radical polymerizations are not living radical polymerizations as there is a non-zero probability of chain termination.
The term living radical polymerization can be used to refer to a hypothetical radical polymerization that occurs without chain termination.
Use of the adjectives pseudo-living, quasi-living, 'living' (within quotation marks) or other terms that containing the word living to describe a radical polymerization with only some living characteristics is deprecated.

Example: Certain polymerizations conducted in confined media which only allow reactions of individual propagating radicals.
