08940 IUPAC Gold Book - catalytic chain termination 10.1351/goldbook.08940 08940 current 1 Chain termination process involving transfer of a group to a reagent (the catalyst) that in turn transfers that group to a propagating species to terminate a chain and regenerate the original reagent. Catalytic chain termination may be observed as a side reaction in certain reversible-deactivation radical polymerizations. propagating species https://goldbook.iupac.org//terms/view/08966 reversible-deactivation radical polymerizations https://goldbook.iupac.org//terms/view/08916 PAC, 2022, 94, 1093.
