A chain model and a sequence model were developed to describe chain and sequence properties for the NM‐CRP of styrene and 4‐methylstyrene in both batch and semi‐batch reactors. The capability of a sequence model to model sequence length and distributions in the course of different processes is demonstrated. The model can also be applied to a Con‐FRP process. Simulation shows a good agreement with experimental data reported in literature. Simulation results indicate that the sequence properties of copolymers prepared by a Con‐FRP process and by an NM‐CRP process can be very similar, but the chain properties are far different. The sequence model can serve as a theoretical tool to understand the importance of sequence length and distributions in radical copolymerization processes.
