Abstract

The polymerization kinetics of the RAFT‐mediated radical polymerization inside sub‐µm particles (D~p~ < 100 nm) is analyzed. The rate retardation by the addition of a RAFT agent in miniemulsion polymerization can be significantly different from that for bulk polymerization. The particle size below which significant rate acceleration occurs can be estimated from a simple equation. It is demonstrated that the reduction of the polymerization rate through the monomer concentration variation effect results from the correlation of concentration variations in monomer and intermediate or, equivalently, monomer and radical.magnified image

## Abstract In the ATRP and SFRP miniemulsion polymerization, a particle size range may exist in which the polymerization rate is larger than that of the corresponding bulk polymerization. Here, MC simulations are applied to clarify the reason for the acceleration. It is shown that the statistical

## Abstract **Summary:** A kinetic analysis of living/controlled radical polymerizations in bulk mediated by RAFT is presented. The main objective is to show how the kinetics of the RAFT process and, in particular, of the RAFT intermediate radical is affecting the overall polymerization rate. Namel
