Abstract

AbstractThe factors that determine the magnitude of the segregation effect in atom transfer radical polymerization (ATRP) in a dispersed system (miniemulsion, emulsion, etc.) have been elucidated by means of simulations based on two‐dimensional Smith–Ewart equations. The segregation effect is not a function of merely the average number of propagating radicals per particle, but also depends on the values of the deactivation and termination rate coefficients. This occurs as a result of these rate coefficients exerting an influence on the distribution of propagating radicals between the particles, which in turn affects the termination rate. The results provide further information as to how one can potentially exploit compartmentalization to improve livingness (end‐functionality) in ATRP in dispersed systems. magnified image
