A mathematical model of reversible addition fragmentation chain transfer (RAFT) living miniemulsion polymerisation based on pseudo-bulk kinetics was developed and validated successfully with experimental data. In this work, in case of large particles synthesis by RAFT miniemulsion polymerisation greater than cross-over size, the developed mathematical model in pseudo-bulk regime reasonably matches with the experimental results and predicts the key polymer properties such as average molecular weight and MWD, average particle size and PSD. Consequently, optimal strategy of semi-batch operation was developed using monomer and RAFT agent feed rate as process variables with specified initial conditions.
