Monte Carlo Simulation on Living Radical Polymerization with RAFT Process

Abstract

Abstract: Monte Carlo simulation is applied, with a high effectiveness and versatility, to the studies on the kinetics and chain length distribution in radical polymerization with RAFTprocess. The results show that the molecular weight the resulting polymers increase linearly with monomer conversion, and the polydispersity is lower than 1.1, a typical feature of living polymerization. The simulation results are in consistent with the experimental results in literature. Additionally, that the molecular weight is proportional to the initial concentration of dithioester, [DSE]₀, and the polymerization rate is [DSE]₀-independent, could be of great help for controlling molecular weight in experiment.

Key words: Living free-radical polymerization, RAFT process, Polydispersity index, Monte Carlo simulation
