✦ Synopsis

&&Living'' free-radical polymerization (LFRP) of styrene is usually performed following two di!erent reaction procedures: by TEMPO-mediated LFRP or by atom transfer radical polymerization. The main di!erence between the previous two processes is related to how the exchange between the active and the dormant state of the polymer chains is performed. A mathematical model suitable for handling both processes is presented. Its validation has been performed by comparison with experimental data taken both from the literature and from our laboratory. These comparisons are intended to cover the most signi"cant reaction conditions a LFRP of styrene can o!er. In spite of a limited parameter "tting, the general reliability of the model has been con"rmed. Thus, the model is thought to have a potential in designing the proper conditions to improve the LFRP.
