The synthesis of monoliths by reversible addition-fragmentation chain transfer (RAFT) copolymerization of styrene and divinylbenzene (DVB) at high-crosslinker content is studied using the recently reported multifunctional polymer molecule approach. The agreement between model predictions, incorporating diffusion-control, and experimental data from CSIRO is good for all cases analyzed. This includes examples with high-crosslinker concentrations, which cause deviation from some of the simplifying assumptions imposed in the model. The production of RAFT-based poly(styrene-co-divinylbenzene) monoliths is successfully modeled using a multifunctional polymer molecule approach. The inclusion of diffusion-controlled effects can produce feasible simulations, but non-isothermal effects in the reacting tubes may have to be taken into account in further refinements to the model.
