Compartmentalization effects in the nitroxide‐mediated radical polymerization of butyl acrylate in a dispersed system using the nitroxide 2,2,6,6‐tetramethylpiperidine‐ N ‐oxyl (TEMPO) at 130 °C have been examined by means of modeling and simulations employing modified Smith–Ewart equations that account for compartmentalization effects on both propagating radicals and free nitroxide species. TEMPO‐mediated acrylate polymerization is known to be problematic, speculated to be mainly related to excessive accumulation of free TEMPO with increasing conversion. The present theoretical results indicate that it may be possible to at least partially overcome this difficulty by careful exploitation of compartmentalization effects in nanoreactors.
