Abstract
Nitroxide-mediated polymerization is now a mature technique, at 35 years of age. During this time, several variants have been developed: electron spin capture polymerization (ESCP), photoNMP (NMP2), chemically initiated NMP (CI-NMP), spin label NMP (SL-NMP), and plasmon-initiated NMP (PI-NMP). This mini-review is devoted to the features and applications of these variants.
