Abstract: Monte Carlo simulation technique was used to simulate the scenarios of the very beginning of a particle in RAFT seeded emulsion polymerization.It was first found that by introducing a high reactive RAFT agent, a large number of free radical need to be captured by the particle before polymerization starts up.The phenomenon was ascribed to the high reactivity of RAFT agent and fast exit of fragmented group of the original RAFT agent.The simulations could be successfully used to explain an unexpected long induction period and polymerization retardation reported.The results of this study will be of particular use in understanding and design of RAFT emulsion polymerization.
